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
In bluetooth driver, there is a missing permission check. This could lead to local information disclosure with no additional execution privileges needed.

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

A missing permission check in the bluetooth driver allows local users to access sensitive information without proper authorization. The vulnerability enables a local attacker to potentially read data they should not have access to, exploiting the lack of access control in the driver's functionality.

MitigationImplement proper permission validation checks in the bluetooth driver to ensure only authorized users/processes can access sensitive operations and data.

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 Android version
    Go to Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADB shell
    Affected if The installed Android version is 10.0, 11.0, or 12.0 exactly as listed in the affected versions
  2. Verify Bluetooth is enabled
    Check if Bluetooth is turned on in Settings > Bluetooth, or run 'settings get global bluetooth_on' via ADB shell
    Affected if Bluetooth is currently enabled on the device
  3. Identify Bluetooth stack components
    Check for running Bluetooth processes via 'ps -A | grep -i blue' or review /system/lib/modules/ for Bluetooth driver modules
    Affected if Bluetooth-related kernel modules or system services are loaded and running
  4. Review Bluetooth permissions and access controls
    Examine Bluetooth system logs using 'logcat -d | grep -i bluetooth' for any access patterns or permission-related messages
    Affected if Bluetooth driver logs show unexpected access patterns or missing permission validation events

You are affected if your Android device runs version 10.0, 11.0, or 12.0 and has Bluetooth enabled, as the missing permission check in the Bluetooth driver could allow unauthorized local access to sensitive Bluetooth data.
