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 ADB server and USB server, there is a possible permission bypass due to an unsafe PendingIntent. This could lead to local information disclosure with User execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android-11Android ID: A-153356209

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

In Android's ADB server and USB server components, an unsafe PendingIntent allows a local malicious application to intercept or manipulate the intent, potentially bypassing permission checks and leading to local information disclosure without user interaction.

MitigationApply Android security patches for Android-11; ensure PendingIntents are created with immutable flags (FLAG_IMMUTABLE) to prevent interception by malicious applications.

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
    Affected if Version equals 11.0 (Android 11)
  2. Verify ADB server component presence
    Check if ADB daemon is running using 'adb devices' or 'ps -A | grep adb' command via ADB shell
    Affected if ADB server is active on Android 11.0 devices
  3. Check USB server component
    Examine USB services via 'dumpsys usb' or check for usb service processes in 'ps -A' output
    Affected if USB server service is running on Android 11.0
  4. Identify PendingIntent usage in system services
    Review system app logs or use security scanning tools that detect unsafe PendingIntent patterns in system services; grep for 'PendingIntent' without FLAG_IMMUTABLE in system service code if source access is available
    Affected if System services create PendingIntents without FLAG_IMMUTABLE flag

Device is affected if running Android 11.0 and uses the ADB server or USB server components with unsafe PendingIntent configurations.
