Microsoft and Google Project Zero researchers announced today a new category of processor vulnerability known as a speculative execution side channel vulnerability, or Speculative Store Bypass, that is closely related to the Spectre Variant 1 vulnerability. Microsoft has also released a security advisory for the new vulnerability.

Impressively, AMD has already released a 5 page whitepaper on the vulnerability, as well as a post on their security updates page outlining that they will be providing updates back to the Bulldozer series of processors. Even more remarkable, is AMD stats that these updates are already in the hands of Microsoft, who is completing final testing and validation and will be released over the standard update process.
