Intel has released microcode updates for a bunch of CPUs (https://downloadcenter.intel.com/download/27431/Linux-Processor-Microcode-Data-File?product=873 here).
However, at least the microcode update for Broadwell-E, cpuid 000406F1 (e.g. Core I7 6900K) is missing as it still contains rev 0xb000021,(2017-03-01), whereas a revision 0xb000025 https://wiki.gentoo.org/wiki/Project:Security/Vulnerabilities/Meltdown_and_Spectre seems to be available. (Note: the microcode files in the latest 20180108 and previous 20171117 for cpuid 000406F1 are identical).
@Intel - can you verify the microcode update file whether all necessary updates are included?
I have also the Intel i7 6900K 14nm and if that CPU also affected, where must I search for the update because I can not find it on the published list.
In the Link from BreakStuff https://downloadcenter.intel.com/download/27431/Linux-Processor-Microcode-Data-File%3Fproduct%3D873 a List for Linux OS, Ubuntu, etc but NOT for Windows
Where is the Windows List?
And what is with the Intel i7 6900K ?
