How to change Image brightness by range of black and white mask in opencv c++

Question

I have two images:

Mat originalImage = imread(addr, IMREAD_UNCHANGED);
Mat maskImage = imread(addr, 0);

Originl Image
Mask Image

maskImage is a grayscale image and size of both images are same.
My question is how can I change brightness in my image by the mask that I have in opencv c++? We have a range between 0 than 255 and 0 it means don't change brightness and 255 is maximum brightness.
Thank you.
