"value": "By default, jailed processes cannot mount filesystems, including nullfs(4). However, the allow.mount.nullfs option enables mounting nullfs filesystems, subject to privilege checks.\n\nIf a privileged user within a jail is able to nullfs-mount directories, a limitation of the kernel's path lookup logic allows that user to escape the jail's chroot, yielding access to the full filesystem of the host or parent jail.\n\nIn a jail configured to allow nullfs(4) mounts from within the jail, the jailed root user can escape the jail's filesystem root."
