I'm not a lawyer, but you are asking for free legal advice, so you get what you pay for. :) No. The GPL (v2 here, the kernel will very likely never go v3 because Linus does not want to re-licence his contributions) grants you an irrevocable licence as long as you do not fall out of compliance with the terms. If AVM wins the courts would be affirming that they have not breached the terms. It would also be up to said copyright holder to not only challenge AVM in court, but figure out how to do it without invalidating the GPL if they win.
