Descriptions
The KEYS subsystem in the Linux kernel before 4.13.10 does not correctly synchronize the actions of updating versus finding a key in the "negative" state to avoid a race condition, which allows local users to cause a denial of service or possibly have unspecified other impact via crafted system calls.
El subsistema KEYS en el kernel de Linux en versiones anteriores a la 4.13.10 no sincroniza correctamente las acciones de actualización con las de detección de una clave en el estado "negative" para evitar una condición de carrera, lo que permite que los usuarios locales provoquen una denegación de servicio (DoS) o, posiblemente, cause otro impacto no especificado mediante llamadas al sistema manipuladas.
