2020.1 IPU – Intel® Processor Microcode (MCU) Updates
Additionally, multiple functional updates took place in Intel® Processor Microcode (MCU), affecting server EX/EP products (incl. D, W, X) and referring to:
  • CLX Patch Load Issue: CLX PRQ. Late patch load overrides perf. MSR (CLX)
  • MD_Clear Operations Errata for CLX: 2019.2 TAA fix allows some data leakage (CLX)
  • Temperature Based Voltage Compensation: Voltage guardband (CLX)
  • OC Mailbox preset: Removes requirement for BIOS loading of the 2019.2 OC Mailbox fix (SKX)
  • ADC/ADDDC: Bug in ADC/ADDDC. M to M timing (SKX/CLX)
  • MCA Recovery: Enable MCA recovery feature on std. RAS SKUs (SKX/CLX) (reboot required)

Higher rates of memory errors have been observed on Intel's Skylake (SKX SP) and Cascade Lake (CLX SP) based server platforms (code named Purley). Mitigations and workarounds are focused in the following area:
  • ECC Coverage: As a result of reallocating metadata bits to other features in SKX & CLX, Intel® modified the ECC algorithms to maximize full device coverage with available bits
  • Rank Switching Speed Path: In 2017, Intel® provided a mitigation for a rank switching speed path marginality via a patch. Subsequent observations by Intel® suggested the patch did not fully address the issue. IPU 2020.1 BIOS option Receive Enable Average is turned off by default (recommended).
  • RAS: Additionally, Intel has discovered three issues (Mesh 2 Mem Timeout, Incomplete Sparing (UEFI) and Rank Sparing Hang (UEFI)) in its Virtual Lockstep RAS (Reliability, Availability, Scalability) features used to enhance memory error correction (ADC & ADDDC). The RAS feature updates include: MCA Recovery, Advanced Memory Test and Post Package Repair.

There were no additional CVEs assigned to these FUNCTIONAL updates.

INTEL-SA-00266: 2020.1 IPU – Intel® SSD Advisory
A potential security vulnerability in Intel® SSD (Solid State Drive) products may allow information disclosure. The detailed description of the vulnerabilities with at least a high or critical CVSS base score is as follows:

NOTE: Intel® Security Advisories INTEL-SA-00330, INTEL-SA-00334 and INTEL-SA-00366 are not part of this 2020.1 Intel Platform Update (IPU).

Recommended Steps for Remediation
Remediation via BIOS Update
Step 1: Determine whether you have an affected system.
Refer to the list of affected Fujitsu products (APL). This list is updated regularly.

Before proceeding, please check the expected availability of the relevant BIOS update package.

Step 2: Download and install the BIOS update package.
To download and install the BIOS update package, please go to the Fujitsu Technical Support page and follow these steps:
  • Select "Select a new Product" (button)
  • Select "Browse for Product"
  • Select "product line"
  • Select "product group" and "product family".
  • Download and install the latest BIOS update package
Remediation via Management Engine (ME) Update
Updating the ME firmware is an alternative to updating the BIOS and used when a BIOS update is not planned. However, it may only be available for some specific Client Computing Devices.

Step 1: Determine whether you have an affected system.
Refer to the list of affected Fujitsu products (APL). This list is updated regularly.

Before proceeding, please check the expected availability of the relevant ME update package.

Step 2: Download the ME update package.
To download the ME update package, please go to the Fujitsu Technical Support page and follow these steps:
  • Select "Select a new Product" (button)
  • Select "Browse for Product"
  • Select "product line"
  • Select "product group" and "product family".
  • Download and install the latest BIOS update package
Step 3: Preparation.
After downloading the .zip file, containing the ME Firmware Update Pack, extract all files/directories/subdirectories in the Firmware.ME directory (\Firmware.ME) of the .zip file to the desired directory on the hard drive.

Step 4: ME Update Procedure.
The "Firmware.ME" directory contains the ME update files which can be used in Windows environment. Run "update.bat" in Windows cmd environment with administrative privileges to start the ME flash procedure. Please choose 32-bit or 64-bit directory if using a Windows 32-bit or a Windows 64-bit installation.

Hints:
  • To run the ME Update procedure using a Windows installation, it is necessary to have the Windows "HECI" driver installed. Please use the Intel® Active Management Technology (Intel® AMT) Driver Package for Windows.
  • To run the ME update procedure, using a Windows PE installation, it is necessary to have the Windows "HECI" driver installed. This can be done at runtime by excuting "drvload.exe \HECI.INF". The "HECI" driver can be extracted from the Intel® Active Management Technology (Intel® AMT) Driver Package for Windows.
