Last modified
CVE-2026-78410 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. A flaw was found in util-linux. Restricted bind mounts take the source path from fstab but do not pin that source before the privileged mount. EPSS estimates a 0.10% chance of exploitation in the next 30 days.
Description
A flaw was found in util-linux. Restricted bind mounts take the source path from fstab but do not pin that source before the privileged mount. A local unprivileged user who can replace the authorized source or a writable ancestor can redirect SUID mount(8) to bind another host directory. If the fstab entry also sets X-mount.owner, X-mount.group, or X-mount.mode, root then changes ownership or mode on that redirected inode.
