Intel seems to change its mind, the latest Microcode Revision Guidance for April 2018 removed 9 architectures from the support list. In Intel’s announcement, the company mentions some security enhancements.
The out-of-band emergency update, KB4100480, was released by Microsoft last week to supplement a patch released in early March to address severe vulnerabilities accidentally introduced by Redmond’s engineers in their January and February security updates for Meltdown on Windows 7 and Windows Server 2008 R2 systems. It seems that this patch is far away from being ‘finished’.
AMD responded in a community post what’s really behind the claims from CTS-Labs – AMD makes it very clear that the issues identified by CTS-Labs research have very less to do with Meltdown & Spectre security holes, but there also telling us that these are associated with the firmware that manages the AMD Secure Processor (PSP) – similar to Intel’s ME. The chipset used in some AM4 and TR4 motherboards as well as others are getting a firmware patches (BIOS updates) for this.
Microsoft, HP, Asus, ASRock & Co. rolling microcode updates out right now, ensure you checked if there is an BIOS update for you or not. Now, a bit late already Windows Build 1607 (Anniversary Update) and 1703 (Creators Update) getting Microcode Updates for all Skylake, Kaby Lake and Coffee Lake systems – the download of KB4091663 & KB4091664 is manual which means you won’t get the Update for your system over Windows Update.
Intel has announced that it has released production microcode updates to OEM manufacturers for Kaby Lake, Coffee Lake, and Skylake platforms. And they have finally given us a schedule and availability table for the microcode revisions that can be found here. This update is already a bit late which means Intel is behind their own schedule but better late than nothing right?
Linus Torvalds released the final version of the first Linux kernel with Meltdown & Spectre fixes, the new version 4.15 comes with over 1000 changesets and this is mostly to address the current security issue. The new Kernel is now more compatible with VR and the free AMDgpu driver got implemented which means AMD Vega GPUs are better supported. You can get, as always, download the latest kernel on kernel.org.
I can’t believe it, even with the Meltdown and Spectre leaks intel is on a new selling record. The stock exploded right after the Intel announcement that there will be a Meltdown & Spectre secure CPU release this year – which btw isn’t enabled by default. According to CEO Brian Krzanich Intel is getting this year new CPUs with an integrated protection.
Intel is currently looking into reports that some of its customers are experiencing reboots in systems that update to the latest firmware for Meltdown & Spectre mitigation. The systems affected are running Broadwell and Haswell processors. However, Intel still recommends end-users should apply the updates for both OS and hardware. Intel needs to straighten this up and the sooner the better.
