CVE-2014-5045 is a vulnerability of currently unknown severity. The mountpoint_last function in fs/namei.c in the Linux kernel before 3.15.8 does not properly maintain a certain reference count during attempts to use the umount system call in conjunction with a symlink, which allows local users to cause a denial of service (memory consumption or use-after-free) or possibly have unspecified other impact via the umount program.. EPSS estimates a 0.49% chance of exploitation in the next 30 days.
