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.

It’s hard to see what this is but if it’s just ducting, they sell end caps for radial ducts at big box stores. You would stick that on the end and wrap it with some aluminum HVAC tape. But it’s not really hurting anything as it is. Probably just vents outside.

I replaced the insulation with some new stuff first, but that is exactly what I ended up doing! It didn’t vent anywhere. The back of the hole backed up to what felt like tar paper. I assume the back of the siding.
The finished product. Thank you for all the advice!
Just because there is an induction stove does not mean ventilation is no longer needed. Cooking produces a lot of things that aren’t necessarily good for you to inhale. Consider adding an appropriately sized hood. You may end up needing this duct.
