It's most likely that this flare comes from the camera front, and is not a leak through the back. The unflared (darker) strip along the edge is the shadow of the film-gate or some part of the mirror box immediately next to the film-gate's edge. There is a small chance that it's light leakage through the finder that's getting past the raised mirror. This would be absent when the camera is held to your eye and worst when shooting with an uncovered waist-level finder or no finder. A light leak from the front of the camera is so unimaginable I can't begin to think where it might originate.
However, I feel most strongly that it's flare from a bright light source just outside the frame that is within the lens's image circle. This bright image would reflect from one of the mirror box's surfaces and you should inspect your camera for a shiny spot or lost paint/baffling material close to the edge of the frame, possibly on the underside of the mirror.
