The company has classified the categories as Ryzenfall, Masterkey, Fallout, and Chimera. CTS-Labs released the information in an unusual fashion. Typically, semiconductor vendors are given 90 days to respond to vulnerabilities before they're disclosed to the public, but CTS-Labs provided AMD with only a 24-hour notice. CTS-Labs states: To ensure public safety, all technical details that could be used to reproduce the vulnerabilities have been redacted from this document. CTS has privately shared this information with AMD, select security companies that can develop mitigations, and the U.S. regulators. What follows is a description of the security problems we discovered and the risks they pose for users and organizations. The unusual nature of the disclosure, and the lack of any supporting evidence, makes it difficult to asses the impact (be it real or imagined) of the alleged AMD security flaws. It is noteworthy that the three different groups of researchers that discovered the Spectre/Melt[...]
