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 application in the mobile phone can read the SNO information of the device, Xiaomi 10 MIUI < 2020.01.15.

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 · moderate confidence

An application on Xiaomi 10 devices running MIUI versions before 2020.01.15 can read the device's SNO (Serial Number) information without proper authorization, allowing unauthorized access to unique device identifiers.

MitigationUpdate Xiaomi 10 devices to MIUI version 2020.01.15 or later to patch the vulnerability that allows unauthorized SNO/serial number disclosure.

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 Xiaomi 10
    Check the device model through Settings > About Phone or by running `getprop ro.product.model` via ADB shell
    Affected if The device model is not Xiaomi 10, then this specific vulnerability does not apply to your device
  2. Check installed MIUI version
    Navigate to Settings > About Phone > MIUI Version, or run `getprop ro.build.version MIUI` via ADB shell to retrieve the exact MIUI build number
    Affected if The MIUI version is less than 2020.01.15 (for example, 2019.12.10 or 2019.11.21), indicating the device is running a vulnerable version
  3. Identify if third-party apps can access SNO
    Review installed applications and their permissions, particularly any sideloaded or untrusted apps requesting read access to device identifiers or serial number information
    Affected if Untrusted or unauthorized applications have permission to read the device serial number (SNO) without user knowledge, confirming the exploitation condition exists

Your Xiaomi 10 device is affected if it runs MIUI versions below 2020.01.15, as the vulnerability allows unauthorized SNO/serial number disclosure to applications.
