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. Verify Android version is 8.0
    Go to Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADB shell
    Affected if Android version shows exactly 8.0 (oreo) - note that versions before or after 8.0 are not affected by this specific CVE)
  2. Confirm the android.view system component is present
    Check that /system/framework/framework.jar exists and contains android.view classes - or verify via 'pm list packages android.view'
    Affected if The android.view package is present and the device is running Android 8.0 (this is the default state for any Android 8.0 device)
  3. Check October 2017 security patch level
    Go to Settings > About Phone > Security patch level, or run 'getprop ro.build.version.security_patch' via ADB shell
    Affected if Security patch level is earlier than October 2017 or the patch level cannot be determined - the vulnerability exists in unpatched Android 8.0 devices

A device is affected if it is running Android 8.0 (exactly version 8.0) and has not received the October 2017 security patch or later patches addressing A-66244132.
