CVE-2026-74699

Host denial of service via replay-state overwrite

Published Aug 22, 2026 · Updated Aug 22, 2026

Memory leak in the Intel Xe driver in Linux kernel 7.0 through 7.1.8 allows local users to exhaust kernel memory via an exec-queue request. exec_queue_set_hang_replay_state() overwrites q->replay_state without rejecting an existing vmemdup_user() allocation, losing the prior pointer without freeing its memory. Reachability requires local access to the Intel Xe DRM exec-queue interface; repeated requests consume kernel memory and interrupt host availability.
