11/25/2023 0 Comments Intel out spectre meltdown chip flawHowever, though Google says it has identified vulnerability with AMD processors, AMD itself says they are not. Intel also points out that multiple chip-providers are affected, including its own processors and those from ARM the latter has said its Cortex-A chipsets are vulnerable. Initial reports cautioned it could add up to a 30-percent hit or greater, though Intel said this afternoon that, for the average user, it would be at most a 2-percent slowdown of their system. What's unclear – and will remain that way until more of the patches hit systems – is just how much of an impact the fixes have on overall performance. MORE What you need to know about Meltdown and Spectre "As this is a new class of attack," Matt Linton, Senior Security Engineer and Pat Parseghian, Technical Program Manager, write, "our patch status refers to our mitigation for currently known vectors for exploiting the flaw." It's worth noting Google's warning that, though it may have patches, there's still the risk of a new Meltdown or Spectre-related exploit being discovered in the future. However, Chrome and Chrome OS users, along with some other Google Cloud Platform product users, may have to do something in order to secure their systems. Google Home and Chromecast, Google Wifi, and OnHub users are also in the clear. Android devices with the latest security update, published earlier this month, are protected, while online services like Google Apps, G Suite, and the Google App Engine require no user action. If you're a Google product user, the important thing you'll probably want to know is whether your products are currently safe or not. Antivirus software is "unlikely in practice" to spot either Meltdown or Spectre attacks at work. If you were hoping to ignore the whole situation, you'll probably be disappointed: most people are likely to be affected by the bug, and there's no trace left of the exploitation even if you are. However, "because of existing public reports and growing speculation in the press and security research community about the issue, which raises the risk of exploitation" it has pulled the trigger early.Ī site,, hosted by the Graz University of Technology – researchers from which also reported both Meltdown and Spectre – has further details. According to Google, the issue was initially intended to be disclosed on January 9th, 2018. While the mechanism is quite different, this technique has echoes of Meltdown/Spectre in that it exploits another workaround Intel has used to speed up the affected chips, said Trey Herr. According to Intel's support pagesone here for the Downfall bug, one here that lays out the status of multiple CVEs across Intel's CPU lineupDownfall affects all processors based on the. Google's Project Zero researcher, Jann Horn, seemingly identified the speculative execution issues independently to other researchers.
