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.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
