What is the difference between an unstable and an unbound orbit of a particle around a black hole?

As far as I understand, an unbound orbit is (informally) a trajectory which does not represent a closed curve (such as an ellipse) around the black hole, and this condition formally corresponds to E>1.

But what does unstable mean then?
