Vulnerability Title
drm/xe/queue: Call fini on exec queue creation fail
Source: NVD (National Vulnerability Database)
Vulnerability Description
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)
