CVE-2022-23220

USBView 2.1 before 2.2 allows some local users (e.g., ones logged in via SSH) to execute arbitrary code as root because certain Polkit settings (e.g., allow_any=yes) for pkexec disable the authentication requirement. Code execution can, for example, use the --gtk-module option. This affects Ubuntu, Debian, and Gentoo.
