CWE-284 10/08/2026
systemd-machined: unprivileged users can terminate arbitrary processes
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

CWE-269 23/03/2026
systemd: Local unprivileged user can trigger an assert
systemd, a system and service manager, (as PID 1) hits an assert and freezes execution when an unprivileged IPC API call is made with spurious data. On version v249 and older the effect is not an assert, but stack overwriting, with the attacker controlled content. From version v250 and newer this is not possible as the safety check causes an assert instead. This IPC call was added in v239, so versions older than that are not affected. Versions 260-rc1, 259.2, 258.5, and 257.11 contain patches. No known workarounds are available.
