They're 3 separate issues. There's a genuine vulnerability (CVE) which has been fixed, there's a follow-up proposal to allow the user to choose which interfaces to bind to, and there's another proposal to disallow ADB over loopback which would cut you off from using ADB on-device. Your problem is with the last one which has nothing to do with the CVE itself.
