Descriptions
Race condition in the install_user_keyrings function in security/keys/process_keys.c in the Linux kernel before 3.8.3 allows local users to cause a denial of service (NULL pointer dereference and system crash) via crafted keyctl system calls that trigger keyring operations in simultaneous threads.
Condición de carrera en la función install_user_keyrings en ??security/keys/process_keys.c en el kernel de Linux anterior a v3.8.3 que permite a usuarios locales provocar una denegación de servicio (desreferencia puntero NULL y caída del sistema) a través de la manipulación del sistema keyctl que dispara operaciones de verificación simultáneamente en varios hilos.
