In the Linux kernel, the following vulnerability has been resolved:
drm/xe/queue: Call fini on exec queue creation fail
Every call to queue init should have a corresponding fini call.
Skipping this would mean skipping removal of the queue from GuC list
(which is part of guc_id allocation). A damaged queue stored in
exec_queue_lookup list would lead to invalid memory reference,
sooner or later.
Call fini to free guc_id. This must be done before any internal
LRCs are freed.
Since the finalization with this extra call became very similar to
__xe_exec_queue_fini(), reuse that. To make this reuse possible,
alter xe_lrc_put() so it can survive NULL parameters, like other
similar functions.
v2: Reuse _xe_exec_queue_fini(). Make xe_lrc_put() aware of NULLs.
(cherry picked from commit 393e5fea6f7d7054abc2c3d97a4cfe8306cd6079)
