-- You are using BIG-IP software versions 12.1.0-12.1.2. -- vCMP guests are deployed in a chassis. -- You configure a new guest running unaffected software alongside an existing or new guest running affected software. In other words, the issue occurs if you mix guests running affected and non-affected versions in a single vCMP host.
