Hello, I don't think that the bug for this problem lies in systemd. It's more a design mistake in docker or oci-register-machine. I have forwarded this issue to the systemd developer team and I don't think they will fix this in the future. In their opinion it's a bug in docker or oci-register-machine: https://github.com/systemd/systemd/issues/3815 by the way.. I would feel glad if the security researchers would first message the developers and then assign a CVE a bug. This is the normal way for a full disclosure. best regards, Christian Rebischke
