In space, nothing. In the atmosphere, may act to dampen any movement of rocket along its short axis (pitch and yaw). Like the feathers on a dart or arrow. Here is a site which describes the movement in rockets .

Prevent the rocket from spinning on it's axis. The fins also have control surfaces (Sometimes) to enable a simple level of control by the Astronaught.
Or, are you talking small rockets - weapons?
If so, then the fins are keeping the rocket in a stable attitude too.
