CVE-2026-101304 · Multiple jail filesystem root escapes
Cette page présente des faits issus de sources publiques. Consultez l’avis original avant toute mise à jour.
When fdescfs(4) was mounted in a jail with the "nodup" option, opening /dev/fd/N returned a descriptor that did not inherit FD_RESOLVE_BENEATH or the Capsicum capability rights of descriptor N. A 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 restriction.
