CVE-2026-43395 Details
Description
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)
A vulnerability in the Linux kernel's Intel graphics driver can lead to a reference leak of synchronization objects. The issue arises in the 'xe_sync_entry_parse' function, which can allocate references to sync objects, fences, and chains before encountering a failure. Some error paths return directly, leaving a partially initialized state and leaking references. The vulnerability has been addressed by routing these error paths through a common cleanup label to properly release the references before returning an error.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been fixed. Instructions for downloading the patched version can be found in the Linux kernel documentation.
