It is doing so by using the PID of the process connecting to the server socket. This is racy. The unix polkit subject is deprecated, but if its used, the UID should be specified as well, so it doesnt get looked up in /proc. I already contacted upstream (Cc) but so far no response. You can find my (untested) proposed patch at: https://bugzilla.suse.com/show_bug.cgi?id=967436 Its probably not the worst issue, but should be fixed nevertheless.
