LIN1023-13078 : Security Advisory - linux - CVE-2025-37951

Created: May 21, 2025    Updated: May 30, 2025
Found In Version: 10.23.30.1
Severity: Standard
Applicable for: Wind River Linux LTS 23
Component/s: Kernel

Description

In the Linux kernel, the following vulnerability has been resolved:

drm/v3d: Add job to pending list if the reset was skipped

When a CL/CSD job times out, we check if the GPU has made any progress
since the last timeout. If so, instead of resetting the hardware, we skip
the reset and let the timer get rearmed. This gives long-running jobs a
chance to complete.

However, when `timedout_job()` is called, the job in question is removed
from the pending list, which means it won't be automatically freed through
`free_job()`. Consequently, when we skip the reset and keep the job
running, the job won't be freed when it finally completes.

This situation leads to a memory leak, as exposed in 1] and [2].

Similarly to commit 704d3d60fec4 ("drm/etnaviv: don't block scheduler when
GPU is still active"), this patch ensures the job is put back on the
pending list when extending the timeout.
