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
Improper access control vulnerability in SearchWidget prior to version 3.3 in China models allows untrusted applications to start arbitrary activity.

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 an improper access control vulnerability in the SearchWidget component on China-specific device models. The vulnerability allows any untrusted application to launch arbitrary activities within the SearchWidget application due to missing or insufficient permission checks on the widget's intent handling. An attacker could exploit this to bypass Android's inter-app communication restrictions and potentially escalate privileges or access sensitive functionality.

MitigationUpdate SearchWidget to version 3.3 or later. If immediate updating is not possible, review the widget's AndroidManifest.xml and implement proper permission checks or set appropriate intent filters to prevent unauthorized activity launches.

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. Identify China-specific Samsung model
    Check device model number and region settings. China-specific models typically have model numbers ending with '0' or '8' (e.g., SM-G9880) and are locked to Chinese carrier networks. Use 'getprop ro.product.model' or check Settings > About Phone > Model Number.
    Affected if Device is a China-specific Samsung model and SearchWidget is installed
  2. Check if SearchWidget is installed
    Run 'pm list packages | grep searchwidget' via ADB shell or check in Settings > Apps for 'com.samsung.android.app.searchwidget' or similar SearchWidget package.
    Affected if SearchWidget package exists on the device
  3. Verify SearchWidget version
    Run 'dumpsys package com.samsung.android.app.searchwidget | grep versionName' via ADB shell, or check the app version in Settings > Apps > SearchWidget > App info.
    Affected if Installed version is lower than 3.3 (for example, 3.2.x, 3.1.x, etc.)
  4. Confirm vulnerable intent handling is present
    Examine the SearchWidget AndroidManifest.xml for exposed intent filters without proper permission checks. Use 'aapt dump badging /path/to/searchwidget.apk' or decompile the APK and inspect AndroidManifest.xml for activity components with 'android:exported=true' that handle search intents.
    Affected if SearchWidget has exported activity components handling intents without android:permission attribute or custom permission checks

User is affected if they are on a China-specific Samsung model with SearchWidget installed at a version lower than 3.3 that exposes unprotected intent-handling activities.

Upgrade available Upgrade to 3.3 or later
Fixed in 3.3
Interim mitigation

Update SearchWidget to version 3.3 or later. If immediate updating is not possible, review the widget's AndroidManifest.xml and implement proper permission checks or set appropriate intent filters to prevent unauthorized activity launches.

Recommended fix High confidence

SearchWidget version 3.3

  1. Open the Galaxy Store app on the Samsung device
  2. Search for "SearchWidget" in the Galaxy Store
  3. Locate the SearchWidget application and check if version 3.3 or later is available
  4. Tap Update to install the latest version (3.3 or later)
  5. Alternatively, check for system updates in Settings > Software update to ensure the widget receives the latest patch
