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. Identify the device model
    Go to Settings > About Phone > Model Number and verify the device is HUAWEI P30
    Affected if The device model is not HUAWEI P30
  2. Check the installed firmware version
    Go to Settings > About Phone > Version and locate the build number or firmware version string
    Affected if Unable to retrieve the firmware version information
  3. Compare version against affected range
    Compare the installed firmware version to 10.1.0.160(C00E160R2P11). The version format typically appears as a build number or in the format shown in About Phone.
    Affected if The installed version is earlier than 10.1.0.160(C00E160R2P11) or the version string is not visible for comparison
  4. Verify the message module is accessible
    Confirm the stock Messaging app or message handling functionality is available on the device
    Affected if The messaging module is present and can receive messages

A user is affected if the device is a HUAWEI P30 running firmware version earlier than 10.1.0.160(C00E160R2P11) with the messaging module enabled.
