AMD is warning about a high-severity CPU vulnerability named SinkClose that impacts multiple generations of its EPYC, Ryzen, and Threadripper processors. The vulnerability allows attackers with Kernel-level (Ring 0) privileges to gain Ring -2 privileges and install malware that becomes nearly undetectable.
Tracked as CVE-2023-31315 and rated of high severity (CVSS score: 7.5), the flaw was discovered by IOActive Enrique Nissim and Krzysztof Okupski, who named privilege elevation attack 'Sinkclose.'
I'd like to see the people that are for kernel-level anticheat running in their PCs 24/7 now.
Vanguard doesn't even let you play the game unless the anticheat has been active since boot afaik.
Every cybersec and even anyone minimally tech-savvy was saying this was a bad idea and what do you know, now we have objective evidence it is in fact a terrible, terrible idea.
