JSON

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.
