Descriptions
fs/pnode.c in the Linux kernel before 4.5.4 does not properly traverse a mount propagation tree in a certain case involving a slave mount, which allows local users to cause a denial of service (NULL pointer dereference and OOPS) via a crafted series of mount system calls.
fs/pnode.c en el kernel de Linux en versiones anteriores a 4.5.4 no cruza adecuadamente la propagación del montaje de árbol en un determinado caso implicando un montaje esclavo, lo que permite a usuarios locales provocar una denegación de servicio (referencia a puntero NULL y OOPS) a través de una serie de llamadas de soporte manipuladas.
