This is a non-story. The US has supplied our missiles and have ownership of that intelligence - they can give the intelligence to anybody they wish to. I suspect they told us before they handed over the information. If they didn't, the people on the JIC who have to worry about these sorts of things would have realised that it was a strong possibility.
It would be a different matter entirely if we had given the US some piece of intelligence over which we had "ownership", and the the US had then given that to the Russians.
