  • Microarchitectural Store Buffer Data Sampling (MSBDS): Store buffers on some microprocessors utilizing speculative execution may allow an authenticated user to potentially enable information disclosure via a side channel with local access. (CVE-2018-12126)
  • Microarchitectural Load Port Data Sampling (MLPDS): Load ports on some microprocessors utilizing speculative execution may allow an authenticated user to potentially enable information disclosure via a side channel with local access. (CVE-2018-12127)
  • Microarchitectural Fill Buffer Data Sampling (MFBDS): Fill buffers on some microprocessors utilizing speculative execution may allow an authenticated user to potentially enable information disclosure via a side channel with local access. (CVE-2018-12130)

MCUs will work in conjunction with updates to Operating System (OS) and Virtual Machine Manage (VMM) software provided by others. Where utilized, Intel® SGX attestation services will report whether the MCU update is applied, beginning June 11, 2019.

Potential Impact:
According to the information provided the potential impact of INTEL-SA-00233 is:

Information Disclosure


Additionally, multiple potential functional issues in Intel® processor microcode (MCU) may cause unpredictable system behavior, platform stability problems or could result in a platform reset. The detailed description of the issues (no CVEs and no CVSS base scores – FUNCTIONAL issue) is as follows:

Amber Lake Y; Broadwell H,U,Y; Coffee Lake H,S,U; KabyLake G,H,S,U,X,Y,RU; Skylake H,S,U/Y,X; Whiskey Lake U

Under complex microarchitectural conditions, software using Intel® TSX (Transactional Synchronization Extensions) may result in unpredictable system behavior. Intel® has only seen this under synthetic testing conditions. Intel® is not aware of any commercially available software exhibiting this behavior.

Amber Lake Y; Broadwell H,U,Y; Coffee Lake H,S,U; Haswell H,U; KabyLake G,H,S,U,X,Y,RU; Skylake H,S,U/Y,X; Whiskey Lake U

"MCE" - Addresses potential platform stability issues which could result in platform reset and MCE (IA32_MCi_STATUS.MSCOD=00FH), (IA32_MCI_ STATUS. MCACOD=0150H).

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(R) Active Management Technology 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 "drvload.exe< Path to HECI.INF>\HECI.INF". The "HECI" driver can be extracted from the Intel(R) Active Management Technology Driver package for Windows.
