Description
A flaw was found in the Linux kernel's drm/xe/guc_submit component. A local attacker could exploit a missing locking mechanism, allowing a non-wedged queue with a zero reference count to be processed concurrently with an asynchronous queue destruction. This can lead to a Use-After-Free (UAF) vulnerability, potentially causing a denial of service.
