CVE-2024-42262

Local denial of service via leaked sync objects

Published Aug 17, 2024 · Updated May 11, 2026

Memory leak in the Linux kernel v3d performance extension 6.8 through 6.10.3 and 6.11-rc1 allows local users to exhaust memory. When a userspace handle-array copy fails partway, the performance-extension loop omits drm_syncobj_put calls for sync objects already acquired. Access to the v3d DRM device and a crafted performance-query submission are required; repeated failures consume kernel memory, producing a service interruption under exhaustion.
