CVE-2026-4948 is fixed in 6 products on 1 platform, first by RHSA-2026:67843, released March 27, 2026. It is not reported as exploited. Patch Radar priority: Routine.
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.
