A jailed process could rename a directory relative to a restricted descriptor, then escape the jail root via fchdir(2).  This requires the directory to reside on a filesystem that is also reachable from the jail's root.\n\nA process in a jail that has received a directory file descriptor from another jail can use these techniques to escape the jail's filesystem root
