    Intel Microcode Revision Guidance for Spectre variant 2 - April 2


    The following table provides details of availability for microcode updates currently planned by Intel. Changes since the previous version are highlighted in yellow.

    LEGEND:

    Production Status:
    • Planning – Intel has not yet determined a schedule for this MCU.
    • Pre-beta – Intel is performing early validation for this MCU.
    • Beta – Intel has released this production signed MCU under NDA for all customers to validate.
    • Production – Intel has completed all validation and is authorizing customers to use this MCU in a production environment.
    • Stopped – After a comprehensive investigation of the microarchitectures and microcode capabilities for these products, Intel has determined to not release microcode updates for these products for one or more reasons including, but not limited to the following:
    • Micro-architectural characteristics that preclude a practical implementation of features mitigating Variant 2 (CVE-2017-5715)
    • Limited Commercially Available System Software support
    • Based on customer inputs, most of these products are implemented as “closed systems” and therefore are expected to have a lower likelihood of
    exposure to these vulnerabilities.

    Pre-Mitigation Production MCU:
    • For products that do not have a Production MCU with mitigations for Variant 2 (Spectre), Intel recommends using this version of MCU. This does not impact mitigations for Variant 1 (Spectre) and Variant 3 (Meltdown).

    STOP deploying these MCU revs:
    • Intel recommends to discontinue using these select versions of MCU that were previously released with mitigations for Variant 2 (Spectre) due to system stability issues.
    • Lines with “***” were previously recommended to discontinue use. Subsequent testing by Intel has determined that these were unaffected by the stability issues and have been re-released without modification.

    The list of CPU families Intel won't patch are:

    • Bloomfield
    • Bloomfield Xeon
    • Clarksfield
    • Gulftown
    • Harpertown Xeon C0
    • Harpertown Xeon E0
    • Jasper Forest
    • Penryn/QC
    • SoFIA 3GR
    • Wolfdale C0
    • Wolfdale M0
    • Wolfdale E0
    • Wolfdale R0
    • Wolfdale Xeon C0
    • Wolfdale Xeon E0
    • Yorkfield
    • Yorkfield Xeon

    They should have at least released microcode updates for all processors based on the Nehalem architecture. And as mentioned in another thread, there is still no mention of most desktop Ivy Bridge or Haswell processors.

    Think they just forgot to list them. Code is the same as mobile. Think so Here's my i3-4150

    All Ivy Bridge in Production, see p.9 of Intel pdf document.
    No BIOS update yet for my Dell desktop

    Most desktop Ivy Bridge processors are not listed in the guidance. But as AndreTen pointed out, the microcode update for mobile Ivy Bridge processors seems to include the desktop processors.

    All that is missing now is an updated MS KB4090007 incorporating the new production releases ...
