Descriptions
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.
La API Crypto en el kernel de Linux anterior a 3.18.5 permite a usuarios locales cargar módulos del kernel arbitrarios a través de una llamada al sistema de enlaces para un socket AF_ALG con un nombre de módulo en el campo salg_name, una vulnerabilidad diferente a CVE-2014-9644.
A flaw was found in the way the Linux kernel's Crypto subsystem handled automatic loading of kernel modules. A local user could use this flaw to load any installed kernel module, and thus increase the attack surface of the running kernel.
