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 Midi, there is a possible way to learn about private midi devices due to a permissions bypass. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android-13Android ID: A-203549963

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

This is a permissions bypass vulnerability in Android's MIDI subsystem that allows a local attacker to discover private MIDI devices that should be hidden from unauthorized applications. The vulnerability enables local privilege escalation without requiring user interaction or additional execution privileges.

MitigationThis is a platform-level vulnerability requiring a fix in Android's framework. Users should apply the latest Android security patches (Android-13 patch level) once available from device vendors.

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
    Run 'adb shell getprop ro.build.version.release' or go to Settings > About Phone > Android version
    Affected if Version equals 13.0 exactly
  2. Check if MIDI feature is available
    Run 'adb shell pm list features | grep midi' to see if the MIDI feature is present on the device
    Affected if MIDI feature is listed as available
  3. Check MIDI service status
    Run 'adb shell dumpsys midi' to see the MIDI service state and any connected devices
    Affected if MIDI service is running or MIDI devices are visible to the system
  4. Check for private MIDI device configurations
    Review any app or system configurations that define MIDI devices as private or restricted access
    Affected if Private or restricted MIDI devices are configured on the device

A device is affected if it is running Android 13.0 and has the MIDI subsystem enabled with any private MIDI device configurations present.
