Kernel crash via invalid V3D syncobj handle
Published Aug 17, 2024 · Updated May 11, 2026
A denial-of-service flaw in Linux 6.8 through 6.10.3 allows local users to crash the kernel through a V3D performance query. In v3d_get_cpu_reset_performance_params, drm_syncobj_find can return NULL for an invalid handle, but the extension stores that unchecked result for later processing. Exploitation requires a local low-privileged user with access to the V3D DRM device and can interrupt availability by crashing the host kernel.
