Linux Distros Unpatched Vulnerability : CVE-2026-4948

medium Nessus Plugin ID 303968

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

- 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. (CVE-2026-4948)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
