I was drilling a hole through the top plate in the attic for Ethernet conduit and got too close to a non load bearing stud for the room below. The hole saw got the head of a nail and left a gap that leaves the wall cavity below visible. The hole through the top of the stud looks to be centered on the 4" edge The wall is finished with drywall on both sides and this is old construction. I'm looking to fill in the hole if only for preventing air flow from the attic and re-secure the stud to the top plate since I would like to arm mount a 26inch tv to the stud because of course its going to be the one I nicked.
What are my options for repair and do I need to be concerned putting a load on it?
