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

high Tenable Self-Hosted Container Security Plugin ID 463591

Description

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

 - 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 attacker-
 controlled target can inherit root's ability to move host processes between cgroups. After a privileged
 operator uses --join-cgroup against that target, an unprivileged user can migrate and terminate unrelated
 root processes. (CVE-2026-78408)

Solution

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