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)
AnalysisAI
Incomplete cleanup in the Linux kernel's DRM/Xe GPU driver allows a local low-privileged user to leak kernel object references (syncobj, fence, chain fence, or user fence) by triggering error paths in xe_sync_entry_parse(), resulting in kernel memory exhaustion and local denial of service. Affected kernels include those shipping the Intel Xe GPU driver from the introducing commit (dd08ebf6c352) up to the fix commits landed in stable series 6.12, 6.18, 6.19, and 7.0. …
