CVSS 3.0
5.5 mediumCVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:HCVE-2017-5577
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.
