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.
