Technical description

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

drm/xe/guc: Keep scheduler timeline name alive

The scheduler keeps a pointer to the timeline name, but q->name

is freed with the exec queue while scheduler fences can still

reference it.

Store the name in struct xe_guc_exec_queue so it shares

the scheduler's RCU-deferred lifetime.

(cherry picked from commit 41075f0eb5dcbd3b065d15f15ef7bbe9315188e8)

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
