CVE-2026-72327

Kernel crash via unchecked indirect BO lookup

Published Aug 15, 2026 · Updated Aug 15, 2026

NULL pointer dereference in the Linux kernel V3D DRM driver from 6.8 allows local users to crash the kernel via an invalid BO handle. The v3d_get_cpu_indirect_csd_params() function stores a failed drm_gem_object_lookup() result in info->indirect without checking for NULL, then the indirect CSD job dereferences it. Access to the V3D DRM submission interface and an indirect CSD job are required; the bounded impact is a kernel crash.
