SUSE CVE-2026-76642

util-linux versions through 2.41.5 and 2.42.2 fail to check mount helper exit status before running post-mount hooks, allowing unprivileged users to execute privileged operations on pre-existing filesystems. Attackers can exploit X-mount.idmap or X-mount.owner hooks to clone filesystems with...

SUSE CVE-2026-78410

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 mount8 to bind another host directory. If the fst...

Astra Linux – Vulnerability in udisks2

A flaw was discovered in udisks2. A local attacker with an active console session can exploit insufficient authorization checking for the “as-user” option in the org.freedesktop.UDisks2.Filesystem.Mount D-Bus method. This allows the attacker to forge the “as-user” parameter, mounting file systems...

util-linux: util-linux: failed external mount helper still runs privileged X-mount post-hooks

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.
