Good question -- but I have to say "almost certainly not", for two reasons.

First, I haven't had any email from Microsoft about this -- and for all that Microsoft has a reputation for being bad at security and not supporting open source software, they do take their responsibilities seriously when it comes to inter-vendor coordination.

Second, the details I've seen relating to this suggest that it relates to connection hashing -- which is relatively new, and thus is unlikely to involve code from the BSD stack which Microsoft imported so many years ago.
