CVE-2025-38152: remoteproc: core: Clear table_sz when rproc_shutdown

In the Linux kernel, the following vulnerability has been resolved: remoteproc: core: Clear table_sz when rproc_shutdown There is case as below could trigger kernel dump: Use U-Boot to start remote processor(rproc) with resource table published to a fixed address by rproc. After Kernel boots up, stop the rproc, load a new firmware which doesn't have resource table ,and start rproc. When starting rproc with a firmware not have resource table, `memcpy(loaded_table, rproc->cached_table, rproc->table_sz)` will trigger dump, because rproc->cache_table is set to NULL during the last stop operation, but rproc->table_sz is still valid. This issue is found on i.MX8MP and i.MX9. Dump as below: Unable to handle kernel NULL pointer dereference at virtual address 0000000000000000 Mem abort info: ESR = 0x0000000096000004 EC = 0x25: DABT (current EL), IL = 32 bits SET = 0, FnV = 0 EA = 0, S1PTW = 0 FSC = 0x04: level 0 translation fault Data abort info: ISV = 0, ISS = 0x00000004, ISS2 = 0x00000000 CM = 0, WnR = 0, TnD = 0, TagAccess = 0 GCS = 0, Overlay = 0, DirtyBit = 0, Xs = 0 user pgtable: 4k pages, 48-bit VAs, pgdp=000000010af63000 [0000000000000000] pgd=0000000000000000, p4d=0000000000000000 Internal error: Oops: 0000000096000004 [#1] PREEMPT SMP Modules linked in: CPU: 2 UID: 0 PID: 1060 Comm: sh Not tainted 6.14.0-rc7-next-20250317-dirty #38 Hardware name: NXP i.MX8MPlus EVK board (DT) pstate: a0000005 (NzCv daif -PAN -UAO -TCO -DIT -SSBS BTYPE=--) pc : __pi_memcpy_generic+0x110/0x22c lr : rproc_start+0x88/0x1e0 Call trace: __pi_memcpy_generic+0x110/0x22c (P) rproc_boot+0x198/0x57c state_store+0x40/0x104 dev_attr_store+0x18/0x2c sysfs_kf_write+0x7c/0x94 kernfs_fop_write_iter+0x120/0x1cc vfs_write+0x240/0x378 ksys_write+0x70/0x108 __arm64_sys_write+0x1c/0x28 invoke_syscall+0x48/0x10c el0_svc_common.constprop.0+0xc0/0xe0 do_el0_svc+0x1c/0x28 el0_svc+0x30/0xcc el0t_64_sync_handler+0x10c/0x138 el0t_64_sync+0x198/0x19c Clear rproc->table_sz to address the issue.

Security readout for executives and security teams

Plain-English summary

CVE-2025-38152 is a Linux kernel availability bug in the remote processor framework. In a specific firmware lifecycle, the kernel can dereference a null pointer and crash. The source describes affected NXP i.MX8MP and i.MX9 systems, so business impact is mainly embedded or edge Linux devices using remoteproc, not general internet-facing servers.

Executive priority

Prioritize patching where Linux devices use remoteproc in production, safety-sensitive, or remotely managed environments. For ordinary servers without remoteproc usage, urgency is lower. Treat this as a reliability and outage-prevention issue rather than a data theft risk based on current evidence.

Technical view

The remoteproc core failed to clear rproc->table_sz during shutdown. After a prior firmware with a resource table is stopped, loading firmware without a resource table can call memcpy using a stale table size while rproc->cached_table is NULL, causing a kernel Oops. The fix clears table_sz in rproc_shutdown.

Likely exposure

Exposure is most likely on Linux systems that use remoteproc to manage auxiliary processors, especially embedded platforms like i.MX8MP and i.MX9. The CVSS vector is local, low-privilege, availability-only. The source bundle does not show broad remote exposure.

Exploitation context

The CVE is not listed as KEV, and the provided sources do not claim active exploitation. The described trigger requires local interaction with remoteproc firmware lifecycle behavior. Evidence supports denial of service through kernel crash, not confidentiality or integrity impact.

Researcher notes

Key condition is stale rproc->table_sz surviving shutdown while cached_table is NULL. The public description names i.MX8MP and i.MX9 observations, but the affected listing is Linux-wide. No exploit maturity, bypass details, or non-kernel workaround is established in the provided sources.

Mitigation direction

  • Update to a Linux kernel containing the linked stable remoteproc fix.
  • Follow your OS or device vendor’s kernel advisory for affected branches.
  • For Debian LTS systems, review the linked Debian announcement and update accordingly.
  • Restrict remoteproc control and firmware-loading access to trusted administrators.
  • Avoid changing remoteproc firmware resource-table behavior on affected systems until patched.

Validation and detection

  • Inventory Linux devices using remoteproc, especially i.MX8MP and i.MX9 platforms.
  • Confirm the running kernel includes the stable fix clearing table_sz on shutdown.
  • Check kernel logs for Oops traces involving rproc_start or memcpy after remoteproc restart.
  • Verify remoteproc sysfs or management paths are not exposed to untrusted users.
  • Run vendor-supported remoteproc lifecycle tests after applying the kernel update.
