You have a point light source behind some walls.
Shadows are the obvious answer however i assume you are using lite and that s not an option.
I am in a room where there is no light and i can see the light coming from the next.
Create a unity primitive cube plane etc sized similarly to your wall remove its collider and in the mesh renderer properties set it to shadows only.
You can simulate this in shaders or use raycasts to see if the light is behind a wall.
On why there is still a slight light in your scene despite the walls that s unity s environment lighting.
