CVE-2025-68228

Kernel crash via NULL blob dereference

Published Dec 16, 2025 · Updated Dec 16, 2025

NULL pointer dereference in Linux kernel 6.16 through 6.17.9 allows local users to crash the kernel through DRM plane format handling. During plane initialization, create_in_format_blob converts a drm_property_create_blob error into NULL, and its caller treats NULL as success and dereferences blob->base.id. Triggering requires local low-privileged access to exercise DRM plane setup on a system using affected kernel code; the bounded consequence is a kernel oops and service interruption.
