It has a law from 1990 which criminalises denying those crimes against humanity covered by the Nuremberg Charter, however that only dealt with trying the Axis powers, so doesn't cover the USSR.
There is then the law that got brought in in 2012 that makes it a crime to deny any genocide recognised as such as by the state. However that law got struck down by a court, and also they might count what happened in the USSR as a mass atrocity rather than a genocide, so it might not have covered it.
