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
Vulnerability of input parameter verification in the motor module.Successful exploitation of this vulnerability may affect availability.

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

Insufficient technical details available. The CVE describes an input parameter verification vulnerability in a motor module with availability impact, scored at CVSS 7.5. No specific affected products, versions, attack vector, or technical exploitation details are provided in the official description.

MitigationImplement robust input validation and sanitization on all parameters entering the motor module; assume network-adjacent attackers may attempt to send crafted inputs to cause denial of service.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 Huawei EMUI version
    On the Huawei device, go to Settings > About Phone > Version to view the EMUI build number. Alternatively, use 'adb shell getprop ro.build.version.emui' via Android Debug Bridge.
    Affected if The displayed EMUI version is exactly 12.0.0 or 13.0.0
  2. Check HarmonyOS version
    On the Huawei device, go to Settings > About Phone > Version to view the HarmonyOS build number. Alternatively, use 'adb shell getprop ro.build.version.harmonyos' via Android Debug Bridge.
    Affected if The displayed HarmonyOS version is exactly 2.0.0, 2.1.0, 3.0.0, 3.1.0, or 4.0.0
  3. Verify motor module presence
    Since specific technical details about the motor module are not provided, consult your device documentation or contact Huawei support to confirm whether a motor module is present and active on the device.
    Affected if A motor module is present and accessible on the device

A user is affected if their device runs EMUI 12.0.0, EMUI 13.0.0, or any of the specified HarmonyOS versions (2.0.0 through 4.0.0) and contains an accessible motor module.
