Found this in a cabinet under the stove. I think it’s old ventilation from before the induction burner was installed. Not sure how to seal it off.

It looks like someone already stuffed it with insulation.
Assuming this is in an unseen location, you don’t have to get fancy. You could put a square of plywood over the hole, screw it into place, then caulk the edges. That should cut down on drafts and keep creepy crawlies out.
