Echo: util-linux: security update to 2.41.5-0+deb13u1+e1

high Tenable Self-Hosted Container Security Plugin ID 458770

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- util-linux is a random collection of Linux utilities. In util-linux 2.39 through 2.41.4 and 2.42 through
2.42.1, the SUID `mount` utility's `hook_owner.c` post-mount hook performs path-based `chmod()` and
`lchown()` operations on a previously validated mount target. A local low-privileged user authorized by an
`/etc/fstab` entry with `user` or `users` and an `X-mount.mode`, `X-mount.owner`, or `X-mount.group`
option can use `renameat2(RENAME_EXCHANGE)` to race a writable ancestor of the target and redirect the
privileged ownership or mode change to a root-owned path, potentially gaining root privileges. This issue
is fixed in 2.41.5 and 2.42.2. (CVE-2026-53612)

Solution

Update the util-linux library and its related packages to version 2.41.5-0+deb13u1+e1 or later.
