23
FAUCET Score

CVE-2014-5045 describes a denial-of-service vulnerability in the Linux kernel, specifically affecting versions prior to 3.15.8, including various Red Hat Enterprise Linux distributions. The flaw in the mountpoint_last function's reference count management during umount operations with symlinks allows local users to trigger memory consumption or use-after-free conditions. With a CVSS score of 6.2 (AV:L/AC:H/Au:N/C:C/I:C/A:C), this vulnerability has a high impact on confidentiality, integrity, and availability, but requires high attack complexity and local access. There is no evidence of active exploitation, publicly available exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
