Low risk0th percentile - higher than 0% of all known CVEs
Summary
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.
Risk Assessment
Risk of killing arbitrary processes by an unprivileged user, potentially leading to system or service disruption.
Recommendation
It is recommended to update systemd-machined to a version containing the fix and to check that unprivileged access to the polkit action is not granted.
