CVE-2024-50144

Local device suspension via duplicate fence finalization

Published Nov 7, 2024 · Updated May 11, 2026

Denial of service in Linux kernel 6.11 allows local users to suspend an Intel Xe graphics device through failed GuC TLB requests. The drm/xe TLB invalidation error path signals a stack fence and then finalizes it again, producing an extra runtime-power reference release. Reachability requires local low-privileged access and the Xe driver path; the resulting premature device suspend interrupts graphics availability.
