Summary
Vulnerability reported (CVE-2026-15060). Risk of unauthorized operations or information disclosure. Exploitable via polkit.
Original description
The description as published by the source.
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-machinepolkit 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
