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
Buffer overflow in Active Management Technology (AMT) in Intel Manageability Engine Firmware 8.x/9.x/10.x/11.0/11.5/11.6/11.7/11.10/11.20 allows attacker with remote Admin access to the system to execute arbitrary code with AMT execution privilege.

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

Buffer overflow vulnerability in Intel Active Management Technology (AMT) firmware versions 8.x through 11.20 allows an attacker with remote administrative access to execute arbitrary code with AMT execution privileges. The vulnerability resides in the Manageability Engine firmware, which operates below the operating system at a privileged hardware level.

MitigationUpdate Intel Manageability Engine Firmware to a patched version provided by Intel through their support channels or enterprise management tools. If AMT is not required, disable it in BIOS/UEFI firmware settings as a defense-in-depth measure.

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 Intel AMT or Manageability Engine is present
    Check system information or BIOS/UEFI settings for Intel Active Management Technology (AMT) or Intel Management Engine (ME) entries. On Windows, this may appear in device manager or system information. On Linux, tools like 'meinfo' or 'intel-mei-dkms' package information may show presence.
    Affected if Intel AMT or Manageability Engine firmware is not present on the system, then this CVE does not apply.
  2. Confirm AMT is enabled
    Access BIOS/UEFI settings during boot and look for Intel AMT or Manageability Engine configuration options. In Windows, check Intel Management Engine interface or enterprise management tools if available.
    Affected if AMT is disabled in BIOS/UEFI and the Manageability Engine is not running, the vulnerability cannot be exploited.
  3. Identify the Intel Manageability Engine firmware version
    Use Intel management tools (Intel ME System Tools, Intel Management Engine Interface driver), or check BIOS/UEFI firmware information page for the ME/AMT firmware version string.
    Affected if The installed version falls within any of these ranges: 8.0.0.0 to 8.1.71.3608, 9.0.0.0 to 9.1.41.3024, 10.0.0.0 to 10.0.55.3000, or equals 11.0, 11.5, 11.6, 11.7, 11.10, or 11.20.
  4. Check if system uses affected Asus Z170 motherboard firmware
    Identify the motherboard model through system information, BIOS startup screen, or physical board labeling. Affected models are: Z170 Premium, Z170 Deluxe, Z170 Pro, Z170 A, Z170 Ar, Z170 E.
    Affected if The system is one of the listed Asus Z170 motherboards, then all firmware versions are affected regardless of Intel ME version.
  5. Verify remote administrative access vector
    Confirm whether network access to AMT web interface or SOL (Serial Over LAN) is exposed. Check if ports 16992-16994 (default AMT ports) are accessible on the network.
    Affected if Remote network access to AMT is available and the system meets version or model criteria above, then it is vulnerable.

A system is affected if it has Intel AMT enabled with vulnerable Manageability Engine firmware (versions listed above) or is an Asus Z170 motherboard model with AMT present, and network access to AMT is available to an attacker.
