AI-suggested
A fix is available and has been applied in the Linux kernel. Users should update to a fixed kernel version containing the referenced commits (e.g., f0af63ffa06306f12592cd3919fad6957b425e1b and others). No additional mitigation steps are indicated.
Description
A vulnerability in the Linux kernel's drm/xe/sync component was fixed by ensuring proper cleanup of partially initialized synchronization objects on parse failure. The flaw involved leaking references due to early returns on error paths without cleanup, potentially causing resource leaks.
