CVE-2026-101305 · Multiple jail filesystem root escapes
Cette page présente des faits issus de sources publiques. Consultez l’avis original avant toute mise à jour.
renameat(2) did not enforce FD_RESOLVE_BENEATH on its directory arguments. 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. 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.
