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

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 vulnerability allows attackers to bypass Factory Reset Protection (FRP) on Samsung mobile devices running Android P (9.0) by exploiting SamsungPay mini. FRP is designed to prevent unauthorized use of a device after a factory reset by requiring the original owner's credentials; this bypass would allow a stolen or拾得 device to be usable by an attacker.

MitigationApply the November 2019 Samsung security update (SVE-2019-15090) which patches the SamsungPay mini FRP bypass. Users should ensure their devices are running the latest Samsung software version.

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 The installed version is Android 9.0 (Pie)
  2. Confirm device is Samsung
    Check the device manufacturer via Settings > About Phone > Manufacturer, or run `getprop ro.product.manufacturer` via ADB
    Affected if The device is made by Samsung (the vulnerability targets SamsungPay mini)
  3. Verify SamsungPay mini is present
    Check installed apps via Settings > Apps > SamsungPay mini, or run `pm list packages | grep samsungpay` via ADB
    Affected if SamsungPay mini package is installed on the device

The device is affected if it is a Samsung device running Android 9.0 with SamsungPay mini installed, as this combination allows the FRP bypass to be exploited during device setup after a factory reset.
