    Microcode Updates für Spectre 3a, 4 und L1TF


    Vor kurzem wurden neue Microcode Updates bereitgestellt für Spectre 3a, 4 und L1TF.

    Warum ist der Intel Core i7-4790K nicht in der Liste der Unterstützten Prozessoren?

    Werden die Updates automatisch verteilt? Bei einem Intel Core i7-3960X und einem Core i7-8550U habe ich auch mit manueller Suche keines der Updates finden können.

    Es gibt zwar noch den Update Catalog, aber da muss man wieder schauen, welche Version passt für mein System.

    Wenn das System x64 ist, dann muss man sich die x64 Variante downloaden, oder wofür ist die x86 Variante?

    Intel Deploys Microcode Update for Spectre Flaw on Skylake

    They were found as twins. When it comes to mitigation though, that is different for both of them as well as for Spectre variants. As you noted, AMD CPUs are not vulnerable to Meltdown and needs no patches for it. Intel CPUs do. These are the KPTI patches for Linux and similar patches for MacOS/Windows. Microcode updates (what this news/thread is about) have nothing to do with Meltdown. Microcode patches are for Spectre 2.

    That was their initial statement. I would like to point out wording there. "Near zero risk" is quite an interesting phrase when it comes to security issues and there are examples from the past where this has come back to bite companies in their asses.

    However, you might want to read the statement update from a week later - 11th. I copy-pasted this directly from your link:
    Second one does. Intel's broken microcode updates saga has all been about this exact Spectre 2 mitigation. AMD states (in their statement quoted above from link you provided. also, you say it does yourself in the quote below) it will release microcode fixes for Spectre 2. I am not sure why you claim it is different.
    That optional part might be interesting. Linus was very annoyed with Intel when their patches had the apparent intent of defaulting Spectre mitigation to being turned off. Now AMD officially says their microcode updates are optional...

    Intel Deploys Microcode Update for Spectre Flaw on Skylake

    Every Gigabyte Board with a BIOS Release after 2018/01/10 as the same "CPU Microcode" description AND includes the first buggy spectre microcode update.

    In fact Gigabyte was pretty quick with the update, they just wrote a bad description.

    Now let's see how much time before they realease the new microcode
