The manager_invoke_notify_message function in systemd 231 and earlier allows local users to cause a denial of service (assertion failure and PID 1 hang) via a zero-length message received over a notify socket.

MEDIUM 5.5EPSS 0.63%

Lower severity and a low EPSS score (0.63%). Track it; it rarely justifies an emergency change on its own.
