Name of the Vulnerable Software and Affected Versions: Linux kernel (affected versions not specified)

Description: The issue is related to a missing lock in the wedged fini function of the drm/xe/guc submit module. This can cause a use-after-free (UAF) condition when a non-wedged queue is accessed concurrently with its destruction. The problem arises because the queue pointer is dereferenced after the lookup, which can lead to UAF if the queue is not wedged. The fix involves holding the submission state lock around the check to ensure the queue is not freed prematurely, thus making the check safe.

Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.
