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 if Samsung Notes is installed
    Open device Settings > Apps > Apps, or use an MDM/EMM console to query installed packages. Look for package name 'com.samsung.android.app.notes' on Galaxy devices.
    Affected if Samsung Notes is not found on the device - not applicable to this CVE.
  2. Identify the installed version of Samsung Notes
    In Settings > Apps > Apps > Samsung Notes, view the version info displayed under the app name. Alternatively, query via ADB: 'adb shell dumpsys package com.samsung.android.app.notes | grep versionName'
    Affected if Unable to determine version - manual verification required.
  3. Compare installed version against 4.4.26.71
    Note the version number shown (format typically shows as x.xx.xx.xx). Check if the version is any release prior to 4.4.26.71 - for example, 4.4.20.55 would be affected.
    Affected if Version is less than 4.4.26.71 - the device is affected by this vulnerability.

A device is affected only if Samsung Notes is installed and its version number is lower than 4.4.26.71.
