CVE-2016-9313 is a denial-of-service vulnerability affecting the Linux kernel before version 4.8.7, specifically within the security/keys/big_key.c component. It arises from improper handling of unsuccessful crypto registration combined with successful key-type registration, allowing local users to trigger a NULL pointer dereference and system panic. With a CVSS score of 7.8 (High), this vulnerability has a low attack complexity and requires no privileges, but does necessitate user interaction. While the potential impact includes high 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.
