CVE-2016-4568

CVE-2016-4568 is a denial-of-service vulnerability affecting the Linux kernel, specifically versions prior to 4.5.3, within the videobuf2-v4l2.c driver. A local attacker can trigger a kernel memory write operation, potentially leading to a system crash or other unspecified impacts, by crafting a VIDIOC_DQBUF ioctl call with a malicious number of planes. Rated as High severity (CVSS 7.8), this vulnerability has a low attack complexity and requires local access, but can result in high impact to confidentiality, integrity, and availability. There is no evidence of active exploitation, publicly available exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
