CVE-2024-46718

Local service interruption via identity VRAM overmapping

Published Sep 18, 2024 · Updated May 11, 2026

Improper VRAM mapping in the Linux kernel 6.8 through 6.10.8 allows local users to interrupt service on affected Intel GPUs. The XE migration setup identity-maps the final VRAM chunk with 1 GiB pages even when usable VRAM is not 1 GiB-aligned, extending the mapping beyond its valid range. Exploitation requires low-privileged local access and XE-managed discrete VRAM; published evidence does not specify whether disruption is a hang, crash, or reboot.
