CVE-2026-4948 (GCVE-0-2026-4948)

Vulnerability from cvelistv5 – Published: 2026-03-27 05:30 – Updated: 2026-09-15 23:44

Title

Firewalld: firewalld: local unprivileged user can modify firewall state due to d-bus setter mis-authorization

Summary

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.

Severity

5.5 (Medium)
