Essentially the brains of your devices, CPUs do the “thinking” and “doing” behind computing — that is, they execute the commands you give and keep your programs running. Far more than just virtual machines, Sponsored item title goes here as designed, 2014 Holiday Gift Guide: The other NSA also knows what you want, Intel’s processor flaw is a virtualization nightmare, Red Hat responds to the Intel processor flaw. That means cybercriminals could exploit Meltdown or Spectre to wreak havoc around the world on a scale similar to that seen with the WannaCry strain of ransomware. “InSpectre is a Free Lightweight Meltdown and Spectre Vulnerability and Performance Checker” Jon Sutton for Game Debate wrote a very nice summary of InSpectre's operation and pointed people to GRC for the download. Spectre and Meltdown are the names given to a trio of variations on a vulnerability that affects nearly every computer chip manufactured in the last 20 years. The vulnerability basically melts security boundaries which are normally enforced by the hardware. Continue with the on-screen directions to fix Windows Update. Meltdown and Spectre work on personal computers, mobile devices, and in the cloud. So their CPU design can be found in products made by Samsung, MediaTek, Qualcomm, and others. The Meltdown and Spectre vulnerabilities extend to such a wide array of devices that you almost certainly are threatened. Added 96 Intel server CPUs, 91 Intel desktop CPUs, and 127 Intel mobile CPUs. Rev. AMD CPUs are found in products sold by Acer, Ryzen, Threadripper, Epyc, and others. Basically, the exploit involves reading memory locations that are supposed to be protected and reserved for use by the computer kernel. The update that helps to mitigate the security vulnerabilities should install automatically, but if after running the PowerShell script, you notice that your device isn't protected, there could be a problem with Windows Update or there could be an antivirus conflict. Also, Safari 11.0.2 includes mitigations against Spectre on macOS. More specifically, all modern processors capable of keeping many instructions in flight are potentially vulnerable. The problem affects nearly all operating systems, such as Windows, Linux, macOS and even Android, as well as virtualized environments such as VMware and Citrix. Updated @ 2018-02-02 : Added 11 Intel server CPUs, 96 AMD server CPUs, 168 AMD desktop CPUs, 77 AMD mobile CPUs, 10 IBM POWER CPUs, 9 HiSilicon Kirin mobile SoCs, 10 MediaTek mobile SOCs, 4 MediaTek digital TV SoCs, and 6 NVIDIA devices to the lists of vulnerable CPUs. You can usually find him with his nose buried in a screen. Colloquially, many people refer to them as Spectre 1 and Spectre 2. Also added 20 mobile SoCs, 9 digital TV or media player SoCs, and 43 industrial SoCs.
