Descriptions

The vc4_get_bcl function in drivers/gpu/drm/vc4/vc4_gem.c in the VideoCore DRM driver in the Linux kernel before 4.9.7 does not set an errno value upon certain overflow detections, which allows local users to cause a denial of service (incorrect pointer dereference and OOPS) via inconsistent size values in a VC4_SUBMIT_CL ioctl call.

La función vc4_get_bcl en drivers/gpc/drm/vc4/vc4_gem.c en el controlador VideoCore DRM en el kernel de Linux en versiones anteriores a 4.9.7 no establece un valor errno sobre ciertas detecciones de desbordamiento, lo que permite a usuarios locales provocar una denegación de servicio (referencia incorrecta al puntero y OOPS) a través de valores de tamaño inconsistentes en una llamada ioctl VC4_SUBMIT_CL.
