CVE-2016-4568 (retired)

Priority
Description
drivers/media/v4l2-core/videobuf2-v4l2.c in the Linux kernel before 4.5.3
allows local users to cause a denial of service (kernel memory write
operation) or possibly have unspecified other impact via a crafted number
of planes in a VIDIOC_DQBUF ioctl call.
Ubuntu-Description
It was discovered that the Video For Linux Two (v4l2) implementation in the
Linux kernel did not properly handle multiple planes when processing a
VIDIOC_DQBUF ioctl(). A local attacker could use this to cause a denial of
service (system crash) or possibly execute arbitrary code.
