Descriptions
The fs_pin implementation in the Linux kernel before 4.0.5 does not ensure the internal consistency of a certain list data structure, which allows local users to cause a denial of service (system crash) by leveraging user-namespace root access for an MNT_DETACH umount2 system call, related to fs/fs_pin.c and include/linux/fs_pin.h.
La implementación de fs_pin en el kernel de Linux en versiones anteriores a 4.0.5 no asegura la consistencia interna de una determinada estructura de datos de lista, lo que permite a usuarios locales provocar una denegación de servicio (caída de sistema) aprovechando acceso root al espacio de nombres de usuario para una llamada de sistema MNT_DETACH umount2, relacionado con fs/fs_pin.c y include/linux/fs_pin.h.
