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
The facial recognition module has a vulnerability in input parameter verification. Successful exploitation of this vulnerability may cause failed facial recognition.

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 · low confidence

The vulnerability involves inadequate input parameter verification within a facial recognition module. This input validation flaw could allow specially crafted or malformed input data to trigger failures in the facial recognition functionality, potentially causing denial-of-service conditions or unexpected behavior.

MitigationImplement robust input validation and sanitization for all parameters processed by the facial recognition module. Validate data types, formats, ranges, and reject any input that does not conform to expected parameters before processing.

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. Check EMUI version installed
    Navigate to Settings > About Phone on the Huawei device and locate the Version or EMUI version field. Record the exact version number displayed.
    Affected if The version listed is exactly 12.0.0
  2. Check HarmonyOS version installed
    Navigate to Settings > About Phone > Version on the Huawei device and record the HarmonyOS version number shown.
    Affected if The version listed is exactly 2.0
  3. Verify facial recognition module is configured
    Go to Settings > Security > Face Recognition (or Settings > Face ID & Passcode on some models). Check if facial recognition has been set up and is available as an unlock method.
    Affected if Facial recognition feature is enrolled and enabled on the device

The device is affected if it runs EMUI 12.0.0 or HarmonyOS 2.0 AND has facial recognition configured as an enrolled feature.
