Descriptions
Race condition in the key_gc_unused_keys function in security/keys/gc.c in the Linux kernel through 3.18.2 allows local users to cause a denial of service (memory corruption or panic) or possibly have unspecified other impact via keyctl commands that trigger access to a key structure member during garbage collection of a key.
Condición de carrera en la función key_gc_unused_keys en security/keys/gc.c en el kernel de Linux hasta 3.18.2 permite a usuarios locales causar una denegación de servicio (corrupción de memoria o pánico) o posiblemente tener otro impacto no especificado a través de comandos keyctl que provocan el acceso a un miembro de la estructura clave durante la recogida de basura de una clave.
A race condition flaw was found in the way the Linux kernel keys management subsystem performed key garbage collection. A local attacker could attempt accessing a key while it was being garbage collected, which would cause the system to crash.
