Both the Intel and AMD modern processors find three new vulnerabilities that, thankfully, are very difficult to exploit.
In 2018, experts discovered the vulnerability that affects Intel, AMD, ARM processors, and millions of devices. The effects of Specter are still being felt to this day, and while these vulnerabilities are difficult to exploit, they are not very defensible.
Cybersecurity researchers have discovered three more vulnerabilities in AMD and Intel processors with micro-op caching. (This is briefly a memory for storing parts of translated instructions.) Researchers at the University of Virginia and the University of California published their discovery in a joint article.
As the article shows, the situation is exacerbated by the fact that none of the updates released for Specter makes it harder for cybercriminals to exploit the flaw. The Phoronix reported by the experts warned of Intel and AMD before publishing their article to be exploited by hackers to steal data from computers errors.
However, no updates have been received so far. This is because the vulnerability is difficult to exploit: hackers must avoid all software and hardware protections to access the micro-op cache.
In addition, manufacturers are not trying to release an update because it would bring with it a significant reduction in performance, which no one dares understandably undertake.
