CVE-2026-43395

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