Severity ?
4.4 (Medium) - CVSS:3.0/AV:L/AC:H/PR:L/UI:R/S:U/C:N/I:N/A:H
Summary
It was discovered systemd does not correctly check the content of PIDFile files before using it to kill processes. When a service is run from an unprivileged user (e.g. User field set in the service file), a local attacker who is able to write to the PIDFile of the mentioned service may use this flaw to trick systemd into killing other services and/or privileged processes. Versions before v237 are vulnerable.
