Upgrade Debian:11 systemd to version 240-1 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.
A use-after-free vulnerability was found in systemd. This issue occurs due to the on_stream_io() function and dns_stream_complete() function in 'resolved-dns-stream.c' not incrementing the reference counting for the DnsStream object. Therefore, other functions and callbacks called can dereference the DNSStream object, causing the use-after-free when the reference is still used later.
