13 Critical Flaws Discovered in AMD Ryzen and EPYC Processors
Source: Hacker News
Security researchers claimed to have discovered 13 critical Spectre/Meltdown-like vulnerabilities throughout AMD's Ryzen and EPYC lines of processors that could allow attackers to access sensitive data, install persistent malware inside the chip, and gain full access to the compromised systems.
All these vulnerabilities reside in the secure part of the AMD's Zen architecture processors and chipsets—typically where device stores sensitive information such as passwords and encryption keys and makes sure nothing malicious is running when you start your PC.
The alleged vulnerabilities are categorized into four classes—RYZENFALL, FALLOUT, CHIMERA, and MASTERKEY—and threaten wide-range of servers, workstations, and laptops running vulnerable AMD Ryzen, Ryzen Pro, Ryzen Mobile or EPYC processors.
