AI-suggested
Until an official fix is available, restrict local user access and monitor for unauthorized changes to firewall configurations. Follow vendor guidance closely once updates are released.
Description
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.
