CVE-2017-7374 is a use-after-free vulnerability in the Linux kernel (before version 4.10.7) affecting the fs/crypto/ component. This flaw allows a local attacker to trigger a denial of service via a NULL pointer dereference or potentially escalate privileges by prematurely freeing cryptographic transform objects when revoking keyring keys used for ext4, f2fs, or ubifs encryption. Rated 7.8 HIGH (CVSSv3.1), it requires local access and low privileges, with no user interaction needed, leading to high impacts on confidentiality, integrity, and availability. There is no known active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage surrounding this vulnerability.
