CVE-2016-4568

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 4.5.3

Description The issue allows local users to cause a denial of service, specifically a kernel memory write operation, or possibly have other unspecified impacts. This is achieved via a crafted number of planes in a VIDIOC DQBUF ioctl call, targeting the videobuf2-v4l2.c file in the Linux kernel.

Recommendations For Linux kernel versions prior to 4.5.3, update to version 4.5.3 or later to resolve the issue. As a temporary workaround, consider restricting access to the VIDIOC DQBUF ioctl call to minimize the risk of exploitation.
