Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Logic bug in Kernel subsystem in Intel CSME before version 11.8.60, 11.11.60, 11.22.60 or 12.0.20, or Intel(R) Server Platform Services before version SPS_E5_04.00.04.393.0 may allow an unauthenticated user to potentially bypass MEBx authentication via physical access.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

A logic bug in the Intel CSME (Converged Security and Manageability Engine) kernel subsystem allows an unauthenticated user with physical access to bypass MEBx (Management Engine BIOS Extension) authentication. The vulnerability affects Intel CSME versions before 11.8.60, 11.11.60, 11.22.60, or 12.0.20, and Intel Server Platform Services before SPS_E5_04.00.04.393.0.

MitigationUpdate Intel CSME firmware to version 11.8.60/11.11.60/11.22.60/12.0.20 or later, or SPS to version SPS_E5_04.00.04.393.0 or later, using Intel's firmware update tools or BIOS updates from the system vendor.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify if Intel CSME is present
    Check system information via `dmidecode` or system BIOS for Intel Management Engine components. Look for Intel ME or Intel CSME in firmware/BIOS output.
    Affected if The system uses Intel CSME firmware and version falls within affected ranges (11.0-11.8.59, 11.10-11.11.59, 11.20-11.22.59, 12.0.0-12.0.19) or SPS firmware is below SPS_E5_04.00.04.393.0
  2. Check Intel CSME firmware version
    Use Intel ME Info Tool (meinfo or Intel Management and Security Status utility) or access MEBx during boot to retrieve the CSME firmware version. Command example: `meinfo - verbose` or check via vendor-provided management tools.
    Affected if The reported CSME firmware version matches one of the vulnerable version ranges: >= 11.0 and < 11.8.60; >= 11.10 and < 11.11.60; >= 11.20 and < 11.22.60; >= 12.0.0 and < 12.0.20
  3. Check Intel SPS firmware version
    Use Intel Server Platform Services firmware tools or server management interfaces (BMC/IPMI) to query the SPS firmware version if the system uses SPS instead of consumer CSME.
    Affected if SPS firmware version is reported as lower than SPS_E5_04.00.04.393.0
  4. Determine if MEBx is configured
    Access the MEBx configuration during boot (typically via Ctrl+P at startup) or check BIOS settings for Intel Management Engine options. Look for MEBx password configuration and enable status.
    Affected if MEBx is enabled and accessible, and the firmware version is within the vulnerable ranges listed above, allowing physical attackers to bypass MEBx authentication

The system is affected if it runs Intel CSME firmware versions 11.0-11.8.59, 11.10-11.11.59, 11.20-11.22.59, or 12.0.0-12.0.19, or SPS firmware below SPS_E5_04.00.04.393.0, with MEBx accessible and enabled.
