CVE-2026-72362

System crash via unchecked child page-table pointer

Published Aug 15, 2026 · Updated Aug 15, 2026

NULL pointer dereference in the Linux kernel 6.8 allows local users to crash systems through the drm/xe page-table walk. The xe_pt_zap_ptes_entry() callback applies container_of() to a NULL child for an unpopulated entry and dereferences the resulting invalid pointer. Reaching the fault requires local low-privileged access and an active Intel Xe graphics driver; the bounded consequence is a kernel or driver crash.
