CVE-2015-1333 on Ubuntu 14.04 LTS (trusty) - medium.
Description:
Memory leak in the __key_link_end function in security/keys/keyring.c in the Linux kernel before 4.1.4 allows local users to cause a denial of service (memory consumption) via many add_key system calls that refer to existing keys. Colin King discovered a flaw in the add_key function of the Linux kernel's keyring subsystem. A local user could exploit this flaw to cause a denial of service (memory exhaustion).
