Buffer overrun issues when tinting image

[alpine latch]

in this code I am using a custom engine with its own image and color data types. I am trying to loop through an images pixel data and adjust each pixel like a tint. My current code gives errors and won't compile

CP_Image tintImage(CP_Image image, int red, int green, int blue) {
    // the color we will be tinting the image with
    CP_Color colorToApplyTint = CP_Color_Create(red, green, blue, 127);
    // the array of pixel data spots
    int arraySize = CP_Image_GetWidth(image) * CP_Image_GetHeight(image);
    // allocate the array memory
    CP_Color* colorArray = malloc(arraySize * sizeof(CP_Color));
    // get image pixel data and put it into the address of the color array
    CP_Image_GetPixelData(image, colorArray);
    // iterate through each pixel
    for (int i = 0; i < arraySize; ++i) {
        // if pixel is not transparent, overlay the tinted color
        if (colorArray[i].a > 0) { // error
            colorArray[i] = colorToApplyTint; // error
        }
    }
    // Put the altered pixel data into a new CP_Image we will return
    CP_Image img = image;
    CP_Image_UpdatePixelData(img, colorArray);
    // Free the array memory
    free(colorArray);
    // finally return the altered image
    return img;
}

I made this code change to fix the error, but it still isn't tinting the image
