NVD Description

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

A flaw was found in firewalld. A local unprivileged user can exploit this vulnerability by mis-authorizing two runtime D-Bus (Desktop Bus) setters, setZoneSettings2 and setPolicySettings. This mis-authorization allows the user to modify the runtime firewall state without proper authentication, leading to unauthorized changes in network security configurations.
