xfs: destroy seen inode bitmap when we fail to add a dirpath
LOLLM observes a memory leak in xchk_dirtree_create_path if we create
the directory path object but appending the name to the path fails.
When this happens, we don't tear down the (empty) seen inode bitmap.
This is a pretty trivial error, but let's not leave logic bombs.
Do the same for a similar bug in xrep_dirtree_create_adoption_path.

scsi: qla2xxx: Fix queue teardown NULL dma_free and bitmap locking
qla25xx_free_req_que() and qla25xx_free_rsp_que() have two pre-existing
bugs exposed on the error path of qla25xx_create_{req,rsp}_que():
1. When dma_alloc_coherent() fails during queue creation, the error
path calls the free function with req->ring / rsp->ring still NULL
(from kzalloc). The unconditional dma_free_coherent() with a NULL
cpu_addr is undefined behavior and can panic.
2. The free functions clear req_qid_map / rsp_qid_map under vport_lock,
but the create functions protect the same bitmaps with mq_lock.
This provides no mutual exclusion. Additionally, the create error
path clears the bit and releases mq_lock before calling the free
function, creating a window where another thread can allocate the
same que_id and have its ha->req_q_map entry clobbered by the
subsequent lockless NULL assignment in the free function.
Fix by:
- Guarding dma_free_coherent() with a NULL check on the ring pointer.
- Using mq_lock (the lock held by all creators) in the free functions
to atomically NULL the map entry and clear the bitmap bit.
- Removing the now-redundant clear_bit blocks from the create error
paths since the free functions handle it atomically.

In the Linux kernel, the following vulnerability has been resolved:
scsi: qla2xxx: Fix use-after-free of qpair work on queue teardown
The response queue MSI-X handler qla2xxx_msix_rsp_q() schedules
qla_do_work() via queue_work(ha->wq, &qpair->q_work). qla_do_work()
dereferences the qpair (vha, rsp) and takes qpair->qp_lock.
During teardown, qla2xxx_delete_qpair() deletes the response queue, which
calls free_irq() in qla25xx_free_rsp_que(), and then frees the queue and
the qpair. free_irq() waits for running hardirq handlers but does not
cancel work already placed on ha->wq. A still-pending q_work then runs
qla_do_work() against the freed qpair and response queue, causing a
use-after-free. This is especially likely during full adapter teardown,
where destroy_workqueue(ha->wq) forces pending work to run after the queue
pairs have been freed.
Flush the work item with cancel_work_sync() in qla25xx_free_rsp_que()
after free_irq() has released the interrupt (so no new work can be
queued) and before the response queue and qpair memory are freed (so the
flushed handler still sees valid memory). Guard on rsp->qpair and ha->wq
to match the INIT_WORK() condition and avoid operating on an
uninitialized work_struct.

In the Linux kernel, the following vulnerability has been resolved:
scsi: qla2xxx: Bound VP index against VP_CTRL IOCB bitmap size
The VP control IOCB selects its target virtual port by setting one bit
in vp_idx_map, a fixed 16-byte (128-bit) array in both
vp_ctrl_entry_24xx and vp_ctrl_entry_24xx_ext. qla25xx_ctrlvp_iocb()
computes map = (vp_index - 1) / 8 and writes vce->vp_idx_map[map]
without checking that map stays within the array.
max_npiv_vports is taken from firmware and only sanitized to a
MIN_MULTI_ID_FABRIC-aligned boundary, so it can legitimately be 191 or
255, and qla24xx_control_vp() only rejects vp_index >= max_npiv_vports.
A vp_index above 128 therefore yields map >= 16 and an out-of-bounds
write of up to 16 bytes past vp_idx_map, corrupting the trailing IOCB
fields (or the adjacent request-ring slot on the 64-byte layout).
Reject a vp_index that cannot be represented in the IOCB bitmap in
qla24xx_control_vp(), and add a defensive ARRAY_SIZE() guard in
qla25xx_ctrlvp_iocb() before the write. Adapters that report the usual
63 or 127 NPIV vports are unaffected.

In the Linux kernel, the following vulnerability has been resolved:
f2fs: accurately adjust free_sections during free_segment_range
In free_segment_range(), MAIN_SECS(sbi) is temporarily reduced by `secs`
to restrict block allocation to the safe remaining main area while valid
blocks in the truncated range are evacuated by GC.
However, FREE_I(sbi)->free_sections tracks the total number of free
sections across the whole filesystem. If any sections within the
truncated range were already free upon entering free_segment_range(),
failing to deduct them from free_sections causes the filesystem to
overestimate available free sections in the active, reduced main area.
This leads to inconsistent free section accounting during GC data
migration and can trigger unexpected allocation failures or assertion
errors when space is tight.
Fix this by calculating the number of already-free sections in the
truncated range, deducting them from free_sections upon entering
free_segment_range(), and restoring them on exit.

In the Linux kernel, the following vulnerability has been resolved:
x86/mm/pat: Acquire init_mm read lock on attribute changes to avoid UAF
A previous commit protected against races between ptdump and CPA collapse,
however one still exists between attribute changes and collapse as reported
by Denis V. Lunev (linked).
When an attribute change arises, a lockless page table walker obtains a PTE
entry, which is later written to via set_pte_atomic():
...
-> change_page_attr_set_clr()
-> __change_page_attr_set_clr()
-> __change_page_attr()
-> _lookup_address_cpa()
-> lookup_address_in_pgd_attr()
-> [ lockless page table walker ]
-> set_pte_atomic()
There is nothing preventing a concurrent CPA collapse which can free the
PTE that was retrieved here, resulting in a use-after-free.
With the mmap write lock taken on init_mm over CPA collapse, resolve this
race by acquiring an mmap read lock on init_mm over
__change_page_attr_set_clr().
This locks across the whole operation over which the walk and the PTE
entry write occurs, solving the race.
It is safe to do this here, as no spinlocks are held upon entry to
__change_page_attr_set_clr().
However, the lock must not be held over an allocation, as allocation can
trigger reclaim and shrinkers may call into CPA recursively, making
deadlocks possible (init_mm -> ... -> fs_reclaim -> init_mm).
A page table is allocated when a huge page needs to be split:
-> change_page_attr_set_clr()
-> __change_page_attr_set_clr()
-> __change_page_attr()
-> split_large_page()
[ pagetable_alloc() ]
-> __split_large_page()
Avoid deadlocks by dropping the mmap lock across pagetable_alloc() in
split_large_page() and track whether this is needed by adding a new
'init_mm_read_locked' flag to struct cpa_data.
This is safe as __split_large_page() (called with locks re-established)
revalidates that the page table entry is the same as it was prior to the
locks being dropped and __change_page_attr() repeats the entire page table
walk whenever a split occurs, so concurrent split and collapse are
accounted for.
Concurrent ptdump is also safe as the lock is only dropped over page table
allocation during which time the page table has not yet been modified.
The CPA_COLLAPSE flag is only set by set_memory_rox(), which exclusively
operates upon vmalloc ranges, and on x86 only within the module mapping
space.
This is important, because some callers directly invoke
__change_page_attr_set_clr(), bypassing this lock. However, none of these
operate within the module mapping space.
* cpa_process_alias() - a recursive helper called by
__change_page_attr_set_clr().
* __set_memory_enc_pgtable() - operates on the direct mapping and (via
__vmbus_establish_gpadl()) the vmalloc mapping space.
* __set_pages_[n]p() - called by set_direct_map_[invalid, default,
valid]_noflush(), __kernel_map_pages() - operates on the direct map.
* kernel_[un]map_pages_in_pgd() - operates on EFI ranges.
This work is based upon Denis V. Lunev's excellent analysis of the bug
with gratitude.

When qla2x00_mem_alloc() fails, qla2x00_probe_one() jumps to

second time. Worse, for the dma_pool members it issued

scsi: qla2xxx: Skip vport under deletion in report ID acquisition
qla24xx_report_id_acquisition() format-1 handling walks ha->vp_list under
vport_slock, takes a vref_count on the matching vport and calls
qla_update_host_map() to register its port id.
A vport teardown via qla24xx_vport_delete() sets VPORT_DELETE, then
qla24xx_disable_vp() removes the vport from the host_map btree and zeroes
vha->d_id (RESET_AL_PA). The vport is only unlinked from vp_list later,
in qla24xx_deallocate_vp_id(), which clears vp_map[idx] (RESET_VP_IDX)
but does not touch host_map. In the window in between, report ID
acquisition can still find the vport on vp_list and call
qla_update_host_map(); with d_id already zeroed it takes the
btree_insert32() path and re-inserts the dying vport into host_map.
Nothing cleans that entry afterwards, so once scsi_host_put() frees the
vha a later host_map lookup dereferences freed memory.
Skip a vport that has VPORT_DELETE set before taking the reference, so it
is neither re-registered nor scheduled for DPC re-registration. This
mirrors the existing guard in qla2x00_alert_all_vps().

In the Linux kernel, the following vulnerability has been resolved:
scsi: qla2xxx: Fix soft lockup polling continuation IOCB signature
qla27xx_copy_multiple_pkt() and qla27xx_copy_fpin_pkt() poll
rsp_q->ring_ptr->signature for RESPONSE_PROCESSED (0xDEADDEAD) to decide
whether the next continuation IOCB has arrived, spinning on cpu_relax()
without advancing the ring or decrementing the entry count while it has
not. response_t::signature lives at byte offset 60, but a continuation
IOCB (sts_cont_entry_t / struct sts_cont_entry_ext) carries raw FC frame
payload at that offset (data[56..59]). A received frame whose payload
bytes happen to equal 0xDEADDEAD is therefore misread as "not yet
arrived", and the loop spins forever in interrupt/DPC context, causing a
CPU soft lockup.
The poll is also unnecessary: callers of qla27xx_copy_multiple_pkt()
(PT_LS4_UNSOL and the NVMe purls path) already gate on
qla_chk_cont_iocb_avail(), which guarantees all entry_count IOCBs are
present before copying begins. The sibling helper
__qla_copy_purex_to_buffer() already drops the signature poll and relies
on the entry_type == STATUS_CONT_TYPE guard instead.
Remove the signature busy-wait from both helpers, keeping the entry_type
guard, and gate the FPIN path with qla_chk_cont_iocb_avail() so it defers
and re-processes on the next interrupt once all continuation IOCBs have
arrived, mirroring the ELS_AUTH_ELS and PT_LS4_UNSOL arms. With this the
signature field is never read on a continuation IOCB, eliminating the
payload-aliasing lockup.

scsi: qla2xxx: Validate BSG request_len before reading vendor_cmd[]
The FC BSG transport allocates job->request via memdup_user() using the
exact user-supplied request_len. For FC_BSG_HST_VENDOR,
fc_bsg_host_dispatch() only guarantees request_len covers msgcode and
vendor_id; it does not account for the vendor_cmd[] flexible array.
qla2xxx then reads the command selector vendor_cmd[0] and, in several
sub-handlers, vendor_cmd[1]/[2] or structures overlaid on the vendor
command area without verifying request_len. A caller holding
CAP_SYS_RAWIO can submit a short request whose vendor_id matches the

mis-select a command or panic).
Add a central guard in qla2x00_process_vendor_specific() so the selector
is always in bounds, restrict the early vendor_cmd[0] read in
qla24xx_bsg_request() to sufficiently long vendor messages, and add
request_len checks to the sub-handlers that read further:

it from the list. This leaves a freed node in fcport->unsol_ctx_head: the
next list_add_tail() for that fcport writes through the freed node, and a
subsequent list_del() can corrupt the list or panic.
Unlink uctx with list_del() before kfree() on the error path, matching the

qla2xxx_process_purls_pkt(). qla2x00_rel_sp() in the failure path only

completion). The qpair qp_lock cannot serialize this per-fcport list since
multiqueue adapters add entries through different qpairs, so a concurrent
add and delete (or two concurrent deletes) can corrupt the list pointers.
Introduce a dedicated per-fcport spinlock, unsol_ctx_lock, initialized in
qla2x00_alloc_fcport(), and take it around every list_add_tail()/list_del()
on unsol_ctx_head. The add nests under the existing qp_lock; no delete path

s390/pai: Support CPU hotplug for PMU PAI
The command 'perf stat -e pai_crypto/CRYPTO_ALL/ -- <command>'
crashes the kernel when CPUs are hotplug added during that run.
Root cause is the missing allocation of per-CPU data structures
for that new CPU. The allocation is dynamic and the first
event that has task context creates such a structure for
each online CPU. This is not sufficient. CPUs may be offline
during event creation and can be set online during the
perf run time. For example commands
# echo 0 > /sys/devices/system/cpu/cpu1/online
# perf stat -e cycles -i -- stress-ng -t10s --matrix X
# sleep 1
# echo 1 > /sys/devices/system/cpu/cpu1/online
Currently without a CPU hotplug handler, that new CPU has no
per-CPU data infrastructure. The scheduler runs PMU call back
function pai_add() to install the PMU support for that CPU before
the task is being scheduled on that new CPU.
In pai_add() instructions
mp = this_cpu_ptr(pai_root[idx].mapptr);
cpump = mp->mapptr;
return a NULL pointer and the result is a kernel panic as variable
cpump is used inside that function.
Add CPU hotplug support for CPU add and delete and create
the necessary per-CPU data infrastructure during CPU hotplug
add processing. Same for CPU hotplug remove.
This is done when the CPU is offline to ensure the data structures
are available when CPU is made online and tasks are scheduled on it.

x86/mm/pat: Allocate split page tables as kernel page tables
A PTE is allocated directly without going through the standard page table
allocation routines (such as pte_alloc_one_kernel()) when the CPA code
splits a large page (__split_large_page()).
This means the page table constructor is never called nor is the page table
marked as a kernel page table.
The former results in the folio associated with the page table not being
marked as a page table (__pagetable_ctor() is never called thus neither is
__folio_set_pgtable()) nor are statistics updated to reflect
it (lruvec_stat_add_folio() is never called).
The latter issue of failing to mark the page table as a kernel page
table (ptdesc_set_kernel() is never called) is far more problematic.
Since commit:
5ba2f0a15564 ("mm: introduce deferred freeing for kernel page tables")
kernel page table freeing has been batched and since the
subsequent commit:
e37d5a2d60a3 ("iommu/sva: invalidate stale IOTLB entries for kernel address space")
IOTLB cache entries for kernel page tables have been invalidated upon
being freed.
Since split page tables are freed without this invalidation, the IOTLB
can contain stale entries for them.
Resolve the issue by using the ordinary PTE allocation API at split time.
This results in these kernel page tables invoking a page table constructor,
and thus requires a page table destructor.
Destructors are not always present, like for early allocated direct map
page tables). Conditionally call pagetable_dtor_free() if the PG_table
folio flag for the ptdesc is set, otherwise we free the page table via
pagetable_free().
Regardless of which path is taken page tables marked as kernel page tables,
which now includes split page tables, take the correct route through
pagetable_free_kernel().
There is a user-visible side effect in that split page tables will appear
in nr_page_table_pages in /proc/vmstat (as do other kernel page tables
allocated after early boot), however this is a positive change.
This issue started being markedly problematic after commit:
5ba2f0a15564 ("mm: introduce deferred freeing for kernel page tables")
so choose this as the Fixes target.

i3c: master: Fix device_register() error path
When device_register() fails in i3c_master_register_new_i3c_devs(),
put_device() is called to drop the reference taken by

release callback i3c_device_release() runs and frees the i3c_device.
Two problems follow from that:
i3c_device_release() does WARN_ON(i3cdev->desc), so it warns because
desc->dev->desc still points back at the descriptor. Clear it before
calling put_device().
After put_device() frees the i3c_device, desc->dev is left pointing at
freed memory, so clear desc->dev as well. That prevents, for example,

In the Linux kernel, the following vulnerability has been resolved:
ksmbd: fix maximum allowed access checks
The DACL permission check looks for an ACE matching the current user and
falls back to the Everyone ACE. It does not consider an Authenticated
Users ACE, even though an authenticated session is a member of that
well-known group.
As a result, opening a file whose access is granted through S-1-5-11 can
incorrectly fail with STATUS_ACCESS_DENIED. Treat an Authenticated Users
ACE as a fallback entry alongside Everyone.
The maximal access calculation also combines access masks from every ACE,
regardless of whether its SID applies to the current user. This can grant
rights belonging to an unrelated principal. Process only ACEs applying to
the user, Everyone, or Authenticated Users, and accumulate allowed and
denied masks in ACL order. Preserve explicitly requested access bits so
they are validated against the resulting maximal mask.
When ACCESS_SYSTEM_SECURITY is denied, report STATUS_PRIVILEGE_NOT_HELD
instead of the generic STATUS_ACCESS_DENIED. Access to the system ACL
requires a security privilege that ksmbd does not grant.
For regular files, include FILE_EXECUTE in maximal access when the client
requested GENERIC_EXECUTE and the DACL grants the complete file-read set.
Keep a direct FILE_EXECUTE request subject to the explicit DACL bit. This
matches the POSIX file ACL mapping without broadening specific execute
requests.
Do not replace rights from an applicable NT ACE with a POSIX ACL entry.

gb_audio_gb_get_topology() fetches a topology blob of a module-supplied

form the control, widget and route section offsets. Those le32 sizes
are never checked against the fetched blob, so a module reporting a
small topology size but large section sizes makes the offsets point
past the allocation, and parsing reads out of bounds.
Reject a topology whose section sizes do not fit within the fetched
size before it is parsed.

RDMA/bnxt_re: Validate udata before executing commands
The destroy callbacks currently zero the udata output after tearing down
driver resources. If the userspace access fails, uverbs preserves the
uobject and allows the destroy callback to run again, even though the
driver resource has already been freed.
Call ib_no_udata_io() before teardown so udata failures are detected
while the resource is still intact, then return success after teardown
completes.
As part of this change, move ib_respond_empty_udata() to the start of
the create and modify flows. While this is not strictly required for
general create flows, as the core layer unwinds uobjects on failure, it
is necessary for create AH. In _rdma_create_ah(), the HW object is
otherwise leaked.

phy: renesas: phy-rcar-gen3-usb2: Fix devm action registration for disabled VBUS regulator
devm_regulator_get_exclusive() initialises the regulator with
enable_count = 1, requiring the consumer to disable it before release.
The devm disable action was previously only registered when the caller
explicitly requested enable, so when the regulator was left in its initial
enabled state without an explicit enable call, the cleanup path skipped
decrementing enable_count, triggering a WARN_ON during regulator
release on device removal.
Fix this by always registering the devm disable action based on the actual
enabled state via regulator_is_enabled(), regardless of whether the
caller requested an explicit enable. This covers both the explicitly
enabled case and the initial state set by devm_regulator_get_exclusive().

perf/x86/intel/pt: Fix stop/start with no update
If pt_event_stop() is called without PERF_EF_UPDATE flag, then
perf_aux_output_end() is not called. A subsequent call to pt_event_start()
will call perf_aux_output_begin() again which violates the rule against
nesting and triggers a WARNING in perf_aux_output_begin().
Originally, pt_event_stop() was never called without PERF_EF_UPDATE,
because the only code paths to do so are from event overflow, and Intel PT
does not do that.
However the introduction of group throttling by commit 9734e25fbf5ae
("perf: Fix the throttle logic for a group") meant that an Intel PT event
could be throttled if it was part of a group. Throttling calls PMU
->stop() / ->start() callbacks without flags.
An example is when AUX area sampling is used. The following commands
hit the issue:
echo 10000 > /proc/sys/kernel/perf_event_max_sample_rate
perf record -F32000 --aux-sample -e '{intel_pt//u,cycles:u}' \
-- bash -c 'for i in `seq 1 100000` ; do true ; done'
Use PERF_HES_UPTODATE to track whether perf_aux_output_begin() and
perf_aux_output_end() are balanced. A cleared PERF_HES_UPTODATE bit
indicates that an AUX output context is still open.
Amend pt_event_start() / pt_event_stop() accordingly so that begin/end
stay balanced:
- In non-snapshot mode, stop() always closes the buffer (the buffer may
have run out of space, and that accounting is done by the update), so
a following start() opens a fresh one as before.
- In snapshot/overwrite mode, stop() without PERF_EF_UPDATE leaves the
buffer open so that pt_event_snapshot_aux() can still copy from it,
and start() then only re-enables tracing instead of calling
perf_aux_output_begin() again.
Note that pt_event_del() calls pt_event_stop() with PERF_EF_UPDATE flag set
(as is required by the documentation), so a final call to
perf_aux_output_end() is assured.

regulator: tps6594: Fix device node reference leaks in multiphase loop
In tps6594_regulator_probe(), the multi-phase configuration loop calls

twice to navigate to the PMIC parent node. None of the acquired node
references (np, intermediate parent, np_pmic_parent) are ever released

Additionally, of_find_node_by_name() can return NULL, but the result was
immediately passed to of_node_full_name() and of_get_parent() without a

Fix this by:
- Adding a NULL check for np after of_find_node_by_name()
- Storing the intermediate parent node in a local variable np_parent

wifi: ath11k: cap out-of-range rx MCS instead of leaving bogus rate
ath11k can receive HT/VHT/HE frames whose reported MCS is above the
maximum that can be expressed in the corresponding mac80211 rate space
(e.g. an HE frame reported with MCS 12, while HE tops out at MCS 11).
The frame itself is valid and decodes correctly, but for such a frame
ath11k_dp_rx_h_rate() leaves rx_status->rate_idx set to the out-of-range
value and never assigns rx_status->encoding, so it stays RX_ENC_LEGACY
from the ath11k_dp_rx_h_ppdu() initialization. Once that frame reaches
mac80211 it trips the rate sanity check and the frame is dropped with a
splat:
ath11k_pci 0000:03:00.0: Received with invalid mcs in HE mode 12
WARNING: CPU: 0 PID: 0 at net/mac80211/rx.c:5433 ieee80211_rx_list+0xb0a/0xe90 [mac80211]
Dropping the frame would discard otherwise valid data, so instead cap the
reported MCS to the maximum the rate space can express and deliver the
frame. Set rx_status->encoding before the range check and assign rate_idx
from the capped value, so a frame with an out-of-range MCS no longer
leaves partial or bogus rate metadata behind. Also downgrade the logging
level since they are not treated as invalid frames now. The only loss is
that such a frame is reported as the capped MCS in the rx rate statistics.

ext4: skip extra isize expansion during mount to prevent deadlock
ext4_try_to_expand_extra_isize() is called from __ext4_mark_inode_dirty()
while holding an active jbd2 handle. During mount (!SB_ACTIVE), the
expand path may move xattrs to external blocks and release ea_inodes via
iput(). When !SB_ACTIVE, iput() calls write_inode_now() which acquires
s_writepages_rwsem, creating a circular lock dependency:
s_writepages_rwsem --> jbd2_handle --> xattr_sem --> s_writepages_rwsem
This can be triggered via:
ext4_process_orphan() -> ext4_truncate() -> ext4_mark_inode_dirty()

or:
ext4_evict_inode() -> ext4_mark_inode_dirty()

Skip expansion when !SB_ACTIVE. This is a minor loss of functionality
(extra isize won't grow for these inodes during mount), which e2fsck

RDMA/core: Fix potential use after free in uverbs_free_dmah()
When accessing a dmah via the netlink path the only synchronization
mechanism for the said dmah is rdma_restrack_get().
Currently, rdma_restrack_del() is invoked at the end of
uverbs_free_dmah(), which is too late, since by that point
vendor-specific resources associated with the dmah might already be
freed. This can leave a short window where the dmah remains accessible
through restrack, leading to a potential use-after-free.
Fix this by moving the rdma_restrack_begin_del() call to the start of
uverbs_free_dmah(), ensuring that the dmah is removed from restrack
before its internal resources are released. This guarantees that no new
users hold references to a dmah that is in the process of destruction.
In addition, this change preserves the intended inverted order
between create and destroy routines: resources are added to
restrack at the end of successful creation, and hence shall be removed
from the restrack first thing during the destruction flow, which keeps
the lifecycle management consistent and predictable.

RDMA/efa: Fix PBL chunk length computation
On register MR, when creating the PBL, if it's an indirect PBL we create

and can hold 510 addresses (EFA_PTRS_PER_CHUNK) and has a 12-byte
control buffer at the end of it holding the next chunk's pointer and its
length.
If the PBL number of pages is a multiple of EFA_PTRS_PER_CHUNK, the
calculated last chunk length is wrongly computed as 0, even though that
chunk is fully populated with 510 real page pointers. This wrong length
is used both to DMA map the chunk and is propagated to the device,
causing the device to see the chunk as empty and reject the memory
registration.
Fix the calculation so it will be performed only if the number of pages
isn't a multiple of EFA_PTRS_PER_CHUNK, if it is, its already handled in
the above loop correctly.
Also prevent out-of-bounds reach in the chunks array in such scenario.
