Severity
7.0 (High) - CVSS:3.0/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
screenresolution-mechanism in screen-resolution-extra 0.17.2 does not properly use the PolicyKit D-Bus API, which allows local users to bypass intended access restrictions by leveraging a race condition via a setuid or pkexec process that is mishandled in a PolicyKitService._check_permission call.
