CVE-2025-15576 Jail chroot escape via fd exchange with a different jail

If two sibling jails are restricted to separate filesystem trees, which is to say that neither of the two jail root directories is an ancestor of the other, jailed processes may nonetheless be able to access a shared directory via a nullfs mount, if the administrator has configured one. In this...

CVE-2025-15547 Jail escape by a privileged user via nullfs

By default, jailed processes cannot mount filesystems, including nullfs4. However, the allow.mount.nullfs option enables mounting nullfs filesystems, subject to privilege checks. If a privileged user within a jail is able to nullfs-mount directories, a limitation of the kernel's path lookup logic...

CVE-2025-15547

The CVE-2025-15547 vulnerability affects FreeBSD jail environments configured with the allow.mount.nullfs option. A privileged user inside a jail can mount nullfs directories, and a kernel path-lookup limitation can let the user escape the jail via chroot, granting access to the host/parent files...
