AV software needs kernel privilidges to have access to everything it needs to inspect, but the actual inspection of that data should be done with no privilidges.
I think most AV companies now have a helper process to do that.
If you successfully exploit the helper process, the worst damage you ought to be able to do is falsely find files to be clean.

Ought. But it depends on the way the communication with the main process is done. I wouldn't be surprised if the main process trusts the output from the parser just a tiny bit too much.
