CVE-2014-0102 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2014-0102):

The keyring_detect_cycle_iterator function in security/keys/keyring.c in the Linux kernel through 3.13.6 
does not properly determine whether keyrings are identical, which allows local users to cause a denial of 
service (OOPS) via crafted keyctl commands.
