Despite AMD CPU patch up, researchers highlight more exploits could be entrance
Electronic computer scientists from TU Dresden have shown IT's possible to green goods a Nuclear meltdown-like exposure in AMD's processors. In case you don't remember, AMD's chips were famously unaffected by the innovational Nuclear meltdown CPU exploits, while Intel's were, so this is maybe surprising news. The new tap was demonstrated connected a Ryzen 7 2700X CPU every bit well as with Epyc 7262 and Threadripper 2990WX silicon.
Don't interest though, AMD has developed a technique to palliate the problem and has recommendations as to how software vendors pot psychoanalyze their code for such vulnerabilities. AMD also expressed how newer, and future processors support extra security features to protect against such exploits.
AMD was given fourth dimension to get a solution in range, because the researchers, Saidgani Musaev and Christof Fetzer, originally shared the vulnerability with AMD back in October 2020 but have only just reported their findings. Thus giving AMD plenty of time to extenuate the problem. AMD referenced the vulnerability in a security bulletin, AMD-SB-1010.
The original research paper, "Transient Execution of Non-Canonical Accesses", showed that Acid+ and Window pane 2 processors were vulnerable to specific code sequences that may lead to information leakage. It has since been shown to touch all of AMD's CPUs. This is a different method to that victimized by Meltdown, which relied on fetching information from the L1 data hive up, but the outcome is "very similar to Nuclear meltdown-type behaviour."
The paper does highlight that AMD's design decisions limit the exploitability of these flaws, especially when compared to Intel's CPUs, but that, "information technology may be possible to use them to amplify some other microarchitectural attacks." So not all good news and so.
Since Spectre and Meltdown appeared along the conniption, both Intel and AMD have been cutting to strengthen the surety of their processors. And it looks like such exploits aren't about to disappear any fourth dimension soon.
Alan has been writing about PC tech since before 3D graphics cards existed, and still vividly recalls having to fight with Microsoft disk operating system just to get games to load. He fondly remembers the killer combo of a Matrox Millenium and 3dfx Hoodoo, and seeing Lara Croft in 3D for the prototypic time. He's very beaming computer hardware has advanced arsenic much as it has though, and is in particular happy when putt the latest M.2 NVMe SSDs, AMD processors, and laptops through their paces. He has a long-lasting Magic: The Gathering obsession only limits this to MTG Orbit these days.
