How to fix?

Upgrade Debian:11 systemd to version 44-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream systemd package and not the systemd package as distributed by Debian. See How to fix? for Debian:11 relevant fixed versions and status.

The rm_rf_children function in util.c in the systemd-logind login manager in systemd before 44, when logging out, allows local users to delete arbitrary files via a symlink attack on unspecified files, related to "particular records related with user session."
