CVE-2026-15060Public exploit

Arbitrary process termination via unchecked supervisor PID

Published Aug 10, 2026 · Updated Aug 10, 2026

Improper access control in affected systemd-machined releases allows local users to terminate arbitrary processes through Varlink requests. vl_method_register() checks ownership of the machine leader but accepts an attacker-supplied supervisor PID reference that Machine.Kill later signals as root. Exploitation requires systemd-machined and an active graphical session whose polkit policy permits register-machine; terminal-only and remote sessions are unaffected.
