CVE-2026-78409

The X-mount.subdir option uses a detached-tree fast path on Linux 6.15 and later and passes the configured subdirectory to opentree with ATSYMLINKNOFOLLOW. That flag does not stop intermediate symlink traversal or keep resolution inside the newly mounted filesystem. A local unprivileged user with...

CVE-2026-78408

The nsenter --join-cgroup option opens the target cgroup.procs file as root and leaves that file descriptor open across later namespace and credential changes and across execve. Because the kernel checks later cgroup migrations using the credentials from the original open, a program run in an...

CVE-2026-76642

When an external mount. helper runs but exits with a nonzero status, libmount still treats the helper invocation as successful and runs privileged post-mount hooks. A local unprivileged user with an /etc/fstab entry that uses the user option together with X-mount.idmap or X-mount.owner/group/mode...

CVE-2026-53614

A flaw was found in util-linux. The mount8 SUID binary does not sanitize the LIBMOUNTFORCEMOUNT2 environment variable before use. A local unprivileged user can set this variable to force mount8 to use the legacy two-step mount2 code path, which applies security restrictions such as nosuid and...

CVE-2026-53613

When an /etc/fstab entry is configured with the user or users option, mount8 validates the target path before performing the mount syscall, creating a Time-of-Check-Time-of-Use TOCTOU window. A local unprivileged user with write access to an ancestor directory of the mount target can swap that...

CVE-2026-53612

A flaw was found in util-linux. When an /etc/fstab entry uses the user option together with X-mount.owner, X-mount.group, or X-mount.mode, mount8 changes ownership or permissions on the mount target after mounting without re-verifying the path. A local unprivileged user can exploit this...
