Descriptions

fs/namespace.c in the Linux kernel before 4.0.2 processes MNT_DETACH umount2 system calls without verifying that the MNT_LOCKED flag is unset, which allows local users to bypass intended access restrictions and navigate to filesystem locations beneath a mount by calling umount2 within a user namespace.

fs/namespace.c en el kernel de Linux en versiones anteriores a 4.0.2 procesa llamadas de sistema MNT_DETACH umount2 sin verificar que el indicador MNT_LOCKED no está establecido, lo que permite a usuarios locales eludir restricciones dedicadas al acceso y navegar a localizaciones de archivos de sistema bajo un montaje llamando a umount2 en un espacio de nombres de usuario.
