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

drm/xe: Fix taking invalid lock on wedge

nothing in this case. It fixes the following splat:

[] xe 0000:bf:00.0: [drm] device wedged, needs recovery

[] ------------[ cut here ]------------

[] DEBUG_LOCKS_WARN_ON(lock->magic != lock)

[] WARNING: CPU: 48 PID: 312 at kernel/locking/mutex.c:564 __mutex_lock+0x8a1/0xe60

...

[] RIP: 0010:__mutex_lock+0x8a1/0xe60

[] mutex_lock_nested+0x1b/0x30

[] xe_guc_submit_wedge+0x80/0x2b0 [xe]
