Sources and claim methodology

Upstream source 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)
