AMD's Ryzen, Epyc security co-processor and chipset have major flaws, researchers claim

Researchers say they’ve discovered serious potential vulnerabilities within AMD’s Ryzen and Epyc chip architectures. AMD said it’s taking the reports seriously, though it wasn’t provided sufficient time to investigate or confirm them before their disclosure. CTS-Labs, a security research company which says it specializes in vulnerabilities within ASICs and other chips, has said it’s discovered four potential attacks , code-named Masterkey, Ryzenfall, Fallout, and Chimera. All would require a program running with local access and administrator privileges to exploit them. AMD confirmed it’s been made aware of the potential vulnerabilities.
