CVE-2026-80915

System hang via unsafe display-page-table allocation

Published Sep 9, 2026 · Updated Sep 9, 2026

Improper DPT allocation in the Linux kernel's xe display driver allows attackers to cause random system hangs during GPU load. The xe_fb_pin.c path can allocate display page tables from unaccounted stolen memory, potentially filling that region, while its VRAM-to-system-memory fallback produces pipe faults and a black screen. Reachability requires the xe graphics path and display-page-table activity; media-GT systems incur additional stolen-memory latency while the GT is in MC6.
