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
Use of Implicit Intent for Sensitive Communication in Smart View prior to Android 16 allows local attackers to access sensitive information.

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

Smart View prior to Android 16 uses implicit intents to transmit sensitive data between components. Implicit intents do not specify a target component, allowing any malicious local app that registers for the same intent action to intercept sensitive information. This is a classic Android intent interception vulnerability where the app fails to use explicit intents or protected broadcast permissions.

MitigationReplace implicit intents with explicit intents that specify the target component by name, or apply signature-level permissions to restrict which apps can receive sensitive broadcasts.

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 OS version
    Go to Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADB shell
    Affected if The Android version is below 16.0 (Android 16)
  2. Identify if Smart View app is installed
    Check app list in Settings > Apps, or run 'pm list packages | grep smartview' via ADB shell
    Affected if The Smart View app is installed and the Android version is below 16.0

A device is affected if it runs Android version below 16.0 and has the Smart View app installed, as the app uses implicit intents that could be intercepted by malicious local applications.

Interim mitigation

Replace implicit intents with explicit intents that specify the target component by name, or apply signature-level permissions to restrict which apps can receive sensitive broadcasts.

Recommended fix High confidence

Android 16.0

  1. Verify the current Android version by navigating to Settings > About Phone > Android version
  2. Ensure all important data is backed up to a secure location
  3. Check for system updates by going to Settings > Software update > Download and install
  4. If an update to Android 16.0 or later is available, download and install it
  5. After the update completes, verify the Android version shows 16.0 or higher to confirm the patch is applied
