Kernel panic via pre-check CRTC dereference
Published Oct 22, 2025 · Updated Oct 22, 2025
NULL-pointer dereference in the Linux kernel STM LTDC driver allows local users to trigger a kernel panic through the DRM CRC path. ltdc_crtc_set_crc_source calls container_of on its struct drm_crtc argument before checking whether that pointer is null. Low-privileged local access and a call path supplying a null CRTC pointer are required; successful exploitation crashes the host without reported data disclosure or modification.
