Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> drm/xe/sync: Cleanup partially initialized sync on parse failure<br /> <br /> xe_sync_entry_parse() can allocate references (syncobj, fence, chain fence,<br /> or user fence) before hitting a later failure path. Several of those paths<br /> returned directly, leaving partially initialized state and leaking refs.<br /> <br /> Route these error paths through a common free_sync label and call<br /> xe_sync_entry_cleanup(sync) before returning the error.<br /> <br /> (cherry picked from commit f939bdd9207a5d1fc55cced5459858480686ce22)
