| Description: | Integer overflow in 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 allows local users to cause a denial of service or possibly have unspecified other impact via a crafted size value in a VC4_SUBMIT_CL ioctl call. Murray McAllister discovered that an integer overflow existed in the VideoCore DRM driver of the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.
