CVE-2016-4568
Published: 23 May 2016
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.
From the Ubuntu Security Team
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.
