CVE-2024-36948

Service interruption via Xe migration integer overflow

Published May 30, 2024 · Updated May 11, 2026

Integer overflow in Linux 6.8 through 6.8.9 allows local users to cause a service interruption through Xe migration operations. The xe_migrate_prepare_vm and emit_pte code multiplies 32-bit page-table indices or offsets by page size before widening the results to 64 bits, allowing wraparound. Reachability requires low-privileged local access and an active Xe graphics migration path; public sources do not specify whether interruption causes a hang, crash, or reboot.
