CVE-2026-46310

System crash via incorrect VSP1 cleanup

Published Jun 8, 2026 · Updated Jun 8, 2026

NULL pointer dereference in affected Linux Kernel releases allows local users able to unload modules to crash Gen 4 VSP1 systems. The VSP1 removal path calls vsp1_drm_cleanup instead of vsp1_vspx_cleanup because cleanup does not select the function matching the detected IP generation. Only systems using the Gen 4 Renesas VSP1 path are exposed, and reaching the fault requires control of kernel-module unloading.
