Echo: util-linux: security update to 2.41.5-0+deb13u1+e2

high Tenable Self-Hosted Container Security Plugin ID 463510

Description

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

- The X-mount.subdir option uses a detached-tree fast path on Linux 6.15 and later and passes the configured
subdirectory to open_tree() with AT_SYMLINK_NOFOLLOW. That flag does not stop intermediate symlink
traversal or keep resolution inside the newly mounted filesystem. A local unprivileged user with an fstab-
authorized X-mount.subdir entry can attach a host path at the intended mountpoint. (CVE-2026-78409)

Solution

Update the util-linux library and its related packages to version 2.41.5-0+deb13u1+e2 or later.
