My wife's 2015 Honda CRV will allow the car to exceed the cruise control's set speed by up to 5 mph before the CVT raises the engine speed to apply engine braking. In my 2016 Subaru BRZ (manual transmission), cruise control would never apply brakes, so if the hill was steep enough that engine breaking was slowing the car, then it could potentially exceed the cruise speed. But it would need a nearly 10% grade to do that in 6th gear at 60 mph.
