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
Insufficient input validation in the subsystem for Intel(R) CSME before versions 11.8.70, 11.11.70, 11.22.70, 12.0.45, 13.0.10 and 14.0.10; Intel(R) TXE before versions 3.1.70 and 4.0.20 may allow a privileged user to potentially enable escalation of privilege, information disclosure or denial of service via local 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

Insufficient input validation in Intel CSME and TXE firmware allows a privileged local user to potentially escalate privileges, disclose information, or cause denial of service. This is a firmware-level vulnerability affecting low-level security subsystems on Intel processors.

MitigationUpdate Intel CSME firmware to versions 11.8.70+, 11.11.70+, 11.22.70+, 12.0.45+, 13.0.10+, or 14.0.10+ and Intel TXE to 3.1.70+ or 4.0.20+ as appropriate for the hardware platform.

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. Verify system has Intel CSME or TXE firmware
    Check system information or Intel utility for the presence of Intel Management Engine (ME) or Trusted Execution Engine (TXE). On Windows, run 'wmic baseboard get product,manufacturer' or use Intel System Information Utility.
    Affected if System does not contain Intel CSME or TXE firmware (not applicable)
  2. Retrieve Intel CSME firmware version
    Use Intel System Information Utility (Intel SIU), Intel Management Engine Interface (MEI) driver with 'wmic /namespace:\\root\wmi PATH MSME_DRV get /all' or check BIOS/UEFI setup screen under 'Advanced' or 'Security' menu for 'Intel Management Engine' version.
    Affected if Installed CSME version matches any of these vulnerable ranges: 11.0-11.8.69, 11.10-11.11.69, 11.20-11.22.69, 12.0-12.0.44, 13.0-13.0.9, or 14.0.0-14.0.9
  3. Retrieve Intel TXE firmware version
    Use Intel System Information Utility, Intel TXE driver information, or check BIOS/UEFI setup screen under 'Advanced' or 'Security' menu for 'Intel Trusted Execution Engine' version.
    Affected if Installed TXE version matches any of these vulnerable ranges: 3.0-3.1.69 or 4.0-4.0.19

System is affected if it contains Intel CSME firmware versions 11.x prior to 11.8.70/11.11.70/11.22.70, 12.x prior to 12.0.45, 13.x prior to 13.0.10, or 14.x prior to 14.0.10; or Intel TXE firmware versions 3.x prior to 3.1.70 or 4.x prior to 4.0.20.
