Creative Commons is based on copyright law. In some countries the rights regarding ones likeness are covered by separate laws and Creative Commons has no influence on that. I suspect that even in the US there is more to it. For example, stock photo agencies treat copyright and model releases as separate things. For any non-editorial images that contain recognizable faces they are in my experience strict about about getting a proper model release.
