CVE-2024-36960

Kernel memory disclosure via oversized fence event length

Published Jun 3, 2024 · Updated Aug 5, 2026

Out-of-bounds read in the Linux kernel's vmwgfx driver allows local users to disclose kernel memory through fence events. The fence-event construction path sets drm_event.length to the larger parent structure instead of drm_vmw_event_fence, so drm_read copies bytes beyond the intended event. Exploitation requires local access to the vmwgfx DRM device and a signaled fence event; the operation reads memory but does not modify it.
