AMD has acknowledged the Ryzenfall vulnerabilities discovered by CTS-Labs, though the chip company believes the flaws can be patched via BIOS updates issued over the next few weeks.
In a blog post authored by AMD’s chief technical officer, Mark Papermaster, AMD confirmed that the four broad classifications of attacks—Masterkey, Ryzenfall, Fallout, and Chimera—are viable, though they require administrative access to the PC or server in question. Third-party protection, such as Microsoft Windows Credential Guard, also serve to block unauthorized administrative access, Papermaster wrote.
