Researchers warn that a bug in AMD’s chips would allow attackers to root into some of the most privileged portions of a computer—and that it has persisted in the company’s processors for decades.
"GhostWrite is the result of an architectural flaw, a hardware bug in the XuanTie C910 and C920 CPU. These are only two of many RISC-V CPUs, but they are widely used for a variety of applications. According to the research team, vulnerable devices include:
Scaleway Elastic Metal RV1, bare-metal C910 cloud instances
