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)
