runc: container escape with malicious config due to /dev/console mount and related races

A flaw was found in runc. CVE-2025-52565 is very similar in concept and application toCVE-2025-31133, except that it exploits a flaw in /dev/console bind-mounts. When creating the /dev/console bind-mount to /dev/pts/$n, if an attacker replaces /dev/pts/$n with a symlink then runc will bind-mount...

FreeBSD : FreeBSD -- Jail escape by a privileged user via nullfs (90071333-fbe5-11f0-a13f-bc241121aa0a)

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the 90071333-fbe5-11f0-a13f-bc241121aa0a advisory. By default, jailed processes cannot mount filesystems, including nullfs4. However, the allow.mount.null...
