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 parenthesized module template expression in the salg_name field, as demonstrated by the vfat(aes) expression, a different vulnerability than CVE-2013-7421.

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 una expresión de plantilla de módulos entre paréntesis en el campo salg_name, tal y como fue demostrado por la expresión vfat(aes), una vulnerabilidad diferente a CVE-2013-7421.

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.
