  * New upstream microcode datafile 20240514
    - Mitigations for INTEL-SA-01051 (CVE-2023-45733)
      Hardware logic contains race conditions in some Intel Processors may
      allow an authenticated user to potentially enable partial information
      disclosure via local access.
    - Mitigations for INTEL-SA-01052 (CVE-2023-46103)
      Sequence of processor instructions leads to unexpected behavior in
      Intel Core Ultra Processors may allow an authenticated user to
      potentially enable denial of service via local access.
    - Mitigations for INTEL-SA-01036 (CVE-2023-45745,  CVE-2023-47855)
      Improper input validation in some Intel TDX module software before
      version 1.5.05.46.698 may allow a privileged user to potentially enable
      escalation of privilege via local access.
    - Fix for unspecified functional issues on 4th gen and 5th gen Xeon
      Scalable, 12th, 13th and 14th gen Intel Core processors, as well as for
      Core i3 N-series processors.

  * New upstream microcode datafile 20240312
    - Mitigations for INTEL-SA-INTEL-SA-00972 (CVE-2023-39368):
      Protection mechanism failure of bus lock regulator for some Intel
      Processors may allow an unauthenticated user to potentially enable
      denial of service via network access.
    - Mitigations for INTEL-SA-INTEL-SA-00982 (CVE-2023-38575):
      Non-transparent sharing of return predictor targets between contexts in
      some Intel Processors may allow an authorized user to potentially
      enable information disclosure via local access.  Affects SGX as well.
    - Mitigations for INTEL-SA-INTEL-SA-00898 (CVE-2023-28746), aka RFDS:
      Information exposure through microarchitectural state after transient
      execution from some register files for some Intel Atom Processors and
      E-cores of Intel Core Processors may allow an authenticated user to
      potentially enable information disclosure via local access.  Enhances
      VERW instruction to clear stale register buffers.  Affects SGX as well.
      Requires kernel update to be effective.
    - Mitigations for INTEL-SA-INTEL-SA-00960 (CVE-2023-22655), aka TECRA:
      Protection mechanism failure in some 3rd and 4th Generation Intel Xeon
      Processors when using Intel SGX or Intel TDX may allow a privileged
      user to potentially enable escalation of privilege via local access.
      NOTE: effective only when loaded by firmware.  Allows SMM firmware to
      attack SGX/TDX.
    - Mitigations for INTEL-SA-INTEL-SA-01045 (CVE-2023-43490):
      Incorrect calculation in microcode keying mechanism for some Intel
      Xeon D Processors with Intel SGX may allow a privileged user to
      potentially enable information disclosure via local access.

  * Mitigates (*only* when loaded from firmware through the FIT)
    CVE-2021-0146, INTEL-SA-00528: VT-d privilege escalation through
    debug port, on Pentium, Celeron and Atom processors with signatures
    0x506c9, 0x506ca, 0x506f1, 0x706a1, 0x706a8
    https://github.com/intel/Intel-Linux-Processor-Microcode-Data-Files/issues/57#issuecomment-1036363145
  * Mitigates CVE-2021-0127, INTEL-SA-00532: an unexpected code breakpoint
    may cause a system hang, on many processors.
  * Mitigates CVE-2021-0145, INTEL-SA-00561: information disclosure due
    to improper sanitization of shared resources (fast-store forward
    predictor), on many processors.
  * Mitigates CVE-2021-33120, INTEL-SA-00589: out-of-bounds read on some
    Atom Processors may allow information disclosure or denial of service
    via network access.
  * Fixes critical errata (functional issues) on many processors
  * Adds a MSR switch to enable RAPL filtering (default off, once enabled
    it can only be disabled by poweroff or reboot).  Useful to protect
    SGX and other threads from side-channel info leak.  Improves the
    mitigation for CVE-2020-8694, CVE-2020-8695, INTEL-SA-00389 on many
    processors.
  * Disables TSX in more processor models.
  * Fixes issue with WBINDV on multi-socket (server) systems which could
    cause resets and unpredictable system behavior
  * Adds a MSR switch to 10th and 11th-gen (Ice Lake, Tiger Lake, Rocket
    Lake) processors, to control a fix for (hopefully rare) unpredictable
    processor behavior when HyperThreading is enabled.  This MSR switch
    is enabled by default on *server* processors.  On other processors,
    it needs to be explicitly enabled by an updated UEFI/BIOS (with added
    configuration logic).  An updated operating system kernel might also
    be able to enable it.  When enabled, this fix can impact performance.
