Changelog

Version: 3.20200609.0ubuntu0.20.04.2 2020-06-10 23:06:30 UTC

  intel-microcode (3.20200609.0ubuntu0.20.04.2) focal-security; urgency=medium

  * REGRESSION UPDATE: revert the tmpfiles snippet to do late
    loading of microcode, this would also happen during package
    upgrades. Also, in the case of a problematic microcode update,
    this would prevent booting using an earlier kernel as the late
    loading would still load the problematic micrcode, forcing the use
    of the 'dis_ucode_ldr' kernel command line option to recover.
    (LP: #1883002)

    - CVE-2020-0543 Special Register Buffer Data Sampling (SRBDS),
      INTEL-SA-00320
    - CVE-2020-0548 Vector Register Sampling, INTEL-SA-00329
    - CVE-2020-0549 L1D Eviction Sampling, INTEL-SA-00329
    - Microcode fixes include update for 0x00050654 to address lockups
      on certain Skylake processors (LP: #1854764)
  * Remaining changes:
    - Ship tmpfiles.d snippet to attempt late loading of microcode
      during boot, in case early loading of microcode did not
      happen. Early microcode loading might not happen if booting
      without initramfs or a missbuilt one.
    - debian/initramfs.hook: Do not override preset defaults from
      auto-exported conf snippets loaded by initramfs-tools.
