CVE-2026-43395: drm/xe/sync: Cleanup partially initialized sync on parse failure

Published May 8, 2026

Updated

In the Linux kernel, the following vulnerability has been resolved:

drm/xe/sync: Cleanup partially initialized sync on parse failure

xesyncentryparse() 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 freesync label and call xesyncentrycleanup(sync) before returning the error.

(cherry picked from commit f939bdd9207a5d1fc55cced5459858480686ce22)
