As we have Bran warg into animals and humans. Can he warg into white walkers or wights?
He has not done it within the books or the films yet. As to feasibility...
It seems unlikely. Bran's ability to warg into humans has thus far been limited to Hodor, an individual of limited mental capacity, and he had great difficulty with that. The White Walkers seem to be fully intelligent, so the odds are that he would not be able to warg into them.
Wights have not shown any great signs of intelligence, but they have shown some small amount of awareness and independence when it comes to fulfilling orders, such as how a reanimated member of the Night Watch knew the way to the Commander's office. This suggests that they probably do have a mind to overcome and additionally, it seems to be a diminished mind, much like an animal or Hodor.
TL;DR, Unlikely and Maybe.
