There may be nothing wrong with the drivers.
(This is exactly how CPU microcode updates work — the CPU “takes receipt” of the new microcode package, and integrity-verifies it internally, before starting to do anything involving updating.)
Fantastic solution! You just gave the attackers a way to stop all security updates to the system.
For most systems, a sensible algorithm would be "keep running the last known good definition, until we get the next known good definition"
In other words: ignore bad updates but keep checking for valid ones. That doesn't mean you've permanently lost the ability to update.
Of course, for some systems, different behavior might make more sense.
