CVE-2013-7421

Published: 31 December 2013

The Crypto API in the Linux kernel before 3.18.5 allows local users to load arbitrary kernel modules via a bind system call for an AF_ALG socket with a module name in the salg_name field, a different vulnerability than CVE-2014-9644.

From the Ubuntu security team

A flaw was discovered in the automatic loading of modules in the crypto subsystem of the Linux kernel. A local user could exploit this flaw to load installed kernel modules, increasing the attack surface and potentially using this to gain administrative privileges.
