CVE-2025-38127: ice: fix Tx scheduler error handling in XDP callback

In the Linux kernel, the following vulnerability has been resolved: ice: fix Tx scheduler error handling in XDP callback When the XDP program is loaded, the XDP callback adds new Tx queues. This means that the callback must update the Tx scheduler with the new queue number. In the event of a Tx scheduler failure, the XDP callback should also fail and roll back any changes previously made for XDP preparation. The previous implementation had a bug that not all changes made by the XDP callback were rolled back. This caused the crash with the following call trace: [ +9.549584] ice 0000:ca:00.0: Failed VSI LAN queue config for XDP, error: -5 [ +0.382335] Oops: general protection fault, probably for non-canonical address 0x50a2250a90495525: 0000 [#1] SMP NOPTI [ +0.010710] CPU: 103 UID: 0 PID: 0 Comm: swapper/103 Not tainted 6.14.0-net-next-mar-31+ #14 PREEMPT(voluntary) [ +0.010175] Hardware name: Intel Corporation M50CYP2SBSTD/M50CYP2SBSTD, BIOS SE5C620.86B.01.01.0005.2202160810 02/16/2022 [ +0.010946] RIP: 0010:__ice_update_sample+0x39/0xe0 [ice] [...] [ +0.002715] Call Trace: [ +0.002452] <IRQ> [ +0.002021] ? __die_body.cold+0x19/0x29 [ +0.003922] ? die_addr+0x3c/0x60 [ +0.003319] ? exc_general_protection+0x17c/0x400 [ +0.004707] ? asm_exc_general_protection+0x26/0x30 [ +0.004879] ? __ice_update_sample+0x39/0xe0 [ice] [ +0.004835] ice_napi_poll+0x665/0x680 [ice] [ +0.004320] __napi_poll+0x28/0x190 [ +0.003500] net_rx_action+0x198/0x360 [ +0.003752] ? update_rq_clock+0x39/0x220 [ +0.004013] handle_softirqs+0xf1/0x340 [ +0.003840] ? sched_clock_cpu+0xf/0x1f0 [ +0.003925] __irq_exit_rcu+0xc2/0xe0 [ +0.003665] common_interrupt+0x85/0xa0 [ +0.003839] </IRQ> [ +0.002098] <TASK> [ +0.002106] asm_common_interrupt+0x26/0x40 [ +0.004184] RIP: 0010:cpuidle_enter_state+0xd3/0x690 Fix this by performing the missing unmapping of XDP queues from q_vectors and setting the XDP rings pointer back to NULL after all those queues are released. Also, add an immediate exit from the XDP callback in case of ring preparation failure.

Security readout for executives and security teams

Plain-English summary

A Linux Intel Ethernet driver flaw can leave XDP transmit queues partially configured after a scheduler failure. The resulting stale state can trigger a kernel protection fault and crash the host. Exploitation requires local, low-privileged access according to the supplied CVSS vector, so internet exposure alone is insufficient.

Executive priority

Prioritize affected high-availability, networking, and multi-user Linux hosts because a kernel crash can disrupt services. Accelerate remediation where untrusted local users can influence XDP configuration. Systems without the ice driver or XDP use are lower priority, but version and configuration evidence should support any exception.

Technical view

The ice driver’s XDP setup callback did not completely roll back changes after Tx scheduler or ring preparation failures. Released XDP queues could remain mapped to q_vectors, and the XDP rings pointer was not reset. Later packet-processing activity could dereference invalid state and cause a kernel general protection fault. The fix completes queue cleanup, clears the pointer, and exits immediately after preparation failure.

Likely exposure

Exposure is most plausible on Linux systems using the ice network driver where XDP programs are loaded or managed. The supplied data marks several kernel versions as affected, but its version formatting is ambiguous. Confirm the exact kernel build, driver usage, XDP configuration, and distribution advisory before declaring a host vulnerable.

Exploitation context

The supplied CVSS 3.1 score is 7.8 with local access, low complexity, low privileges, and no user interaction. The bundle documents a kernel crash during failed XDP queue configuration. It does not establish remote reachability or a reliable attack path. The CVE is not listed as KEV, and no supplied source reports active exploitation.

Researcher notes

The failure is an incomplete error-path rollback in ice XDP queue setup. The supplied trace demonstrates a general protection fault after VSI LAN queue configuration failed. Although the CVSS vector claims confidentiality, integrity, and availability impact, the narrative directly demonstrates only a crash. Exact vulnerable and fixed release boundaries cannot be reconstructed confidently from the flattened version list.

Mitigation direction

  • Install a vendor-supported kernel containing the applicable linked stable fix.
  • Check distribution or appliance guidance for the exact corrected release.
  • Restrict who can load or reconfigure XDP programs until remediation.
  • Avoid unsupported kernel builds where update provenance cannot be verified.

Validation and detection

  • Inventory kernel versions and identify systems using the ice driver.
  • Determine whether XDP programs are loaded on affected network interfaces.
  • Map installed builds against vendor advisories and the linked stable commits.
  • Review kernel logs for ice queue-configuration failures or protection faults.
  • After updating, confirm the running kernel includes the applicable fix.
