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
HUAWEI Mate 20 versions earlier than 10.0.0.188(C00E74R3P8) have a buffer overflow vulnerability in the Bluetooth module. Due to insufficient input validation, an unauthenticated attacker may craft Bluetooth messages after successful paring, causing buffer overflow. Successful exploit may cause code execution.

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 the Bluetooth module of HUAWEI Mate 20 devices due to insufficient input validation. An attacker who has successfully paired with the target device can craft malicious Bluetooth messages that overflow a buffer, potentially leading to code execution.

MitigationUpdate HUAWEI Mate 20 to version 10.0.0.188(C00E74R3P8) or later which contains the fix for this vulnerability.

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. Confirm device model is Huawei Mate 20
    Check the device settings: Go to Settings > About Phone > Model Number, or run `getprop ro.product.model` via ADB shell
    Affected if Model number is not Huawei Mate 20 (this vulnerability only affects Mate 20)
  2. Check firmware version
    Navigate to Settings > About Phone > Version, or run `getprop ro.build.version.emui` and `getprop ro.build.version.huawei` via ADB shell
    Affected if Firmware version is earlier than 10.0.0.188(C00E74R3P8)
  3. Verify Bluetooth is enabled
    Check Settings > Bluetooth, or run `settings get global bluetooth_on` via ADB shell
    Affected if Bluetooth is enabled - the vulnerability is exploitable when Bluetooth is active and paired with the attacker

Device is affected only if it is a Huawei Mate 20 with firmware version below 10.0.0.188(C00E74R3P8) and Bluetooth is enabled and paired with an attacker.
