Yup, the 2 black plastic trims on the sides of the windshield. One screw is hidden behind the rubber door trim, the other I think you need to pop your fake air cover to access.

Either double sided tape, RTV silicone, or the black mastic that mirror guys use will cure the buzz.

Leaking is prob something else. Most common culprit are blocked sunroof drain holes (if you have sunroof), and the front marker lights (use black RTV silicone).
