Lower severity and a low EPSS score (0.08%). Track it; it rarely justifies an emergency change on its own.
Description
When systemd-machined >= v259 (or v258 with a custom `polkit` policy that allows `register-machine` access) is running on a desktop system, an unprivileged user logged in a desktop graphical session can kill arbitrary processes, even privileged ones. - versions older than v259 are not affected, unless unprivileged access is granted for the `register-machine` polkit action via a local, custom policy config file - versions older than v258 are not affected - unrelated to the systemd service manager (pid 1 or user session managers) - systemd-machined is not typically installed by default, and is typically in an optional, separate package (e.g.: systemd-container) - terminal-only or remote sessions (e.g.: ssh) are not affected
