You must have non-combustible materials around the stove....all around the stove. The back edge of the stove provides no protection at all. Remove the paneling and install a good sheet of stainless steel (to match the stove finish) up to the cabinet above. I would also look into installing some steel under that cabinet to allow you to keep it clean and out of the line of fire should you ever experience a grease fire. The new cabinet next to the stove should have a non-combustible counter as well.
