CVE-2024-49876

Local kernel compromise via deferred queue destruction

Published Oct 21, 2024 · Updated Aug 5, 2026

Use-after-free in the Linux kernel drm/xe driver allows local users to corrupt kernel memory through execution-queue teardown. The driver schedules final queue destruction on a system workqueue that can outlive the driver instance, leaving work to dereference freed device and GuC state. Any local user with render-node access can drive queue creation and destruction; exploitation can disclose or modify kernel memory or crash the host.
