CVE-2026-4948: Incorrect Execution-Assigned Permissions in Red Hat Red Hat Enterprise Linux 10
CVE-2026-4948 is a vulnerability in the firewalld component of Red Hat Enterprise Linux 10. It allows a local unprivileged user to exploit mis-authorized runtime D-Bus setters, specifically setZoneSettings2 and setPolicySettings, to modify the runtime firewall state without proper authentication. This results in unauthorized changes to network security configurations. The vulnerability has a CVSS score of 5. 5, indicating medium severity. There are no known exploits in the wild at this time. No patch or remediation details are provided in the vendor advisory content.
AI Analysis
Technical Summary
This vulnerability in Red Hat Enterprise Linux 10's firewalld arises from incorrect execution-assigned permissions on two runtime D-Bus setters: setZoneSettings2 and setPolicySettings. A local unprivileged user can leverage this mis-authorization to alter the runtime firewall state without authentication, potentially changing network security settings improperly. The CVSS 3.1 vector indicates local attack vector, low attack complexity, low privileges required, no user interaction, unchanged scope, no confidentiality impact, high integrity impact, and no availability impact.
Potential Impact
The impact is unauthorized modification of the runtime firewall state by a local unprivileged user, which can lead to improper network security configurations. This affects the integrity of the firewall settings but does not impact confidentiality or availability. There are no reports of exploitation in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the Red Hat advisory at https://access.redhat.com/security/cve/CVE-2026-4948 for current remediation guidance. Until an official fix is available, restrict local user access where possible to limit exploitation potential.
