UBUNTU-CVE-2025-37951: Medium severity ubuntu/linux-hwe-edge vulnerability

Q: What conditions are required for this issue to occur?

A CL or CSD GPU job must time out while the GPU is still making progress, causing the driver to skip a hardware reset and extend the timeout. The affected job is then not returned to the pending list, so it is not freed after completion.

Q: What is the practical impact of successful triggering?

The result is a kernel memory leak associated with the V3D DRM driver's handling of long-running GPU jobs. The provided severity vector indicates local access and low privileges are required, with availability impact but no stated confidentiality or integrity impact.

Q: Which Ubuntu kernel packages are listed as affected?

The listed packages are linux-aws-fips, linux-azure-fips, linux-fips, linux-gcp-fips, linux-azure, linux-gcp, linux-azure-fde, and linux-realtime.

Q: How can an administrator determine whether a system may be affected?

Check whether the system uses one of the listed Ubuntu kernel packages and whether workloads use the V3D DRM GPU driver with CL or CSD jobs that can time out while continuing to make progress. The provided data does not include affected or fixed package version numbers.

Updated

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 timedoutjob() is called, the job in question is removed from the pending list, which means it won't be automatically freed through freejob(). 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.
