CVE-2019-20609
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 · uneditedAn issue was discovered on Samsung mobile devices with P(9.0) software. Attackers can use Smartwatch to view Secure Folder notification content. The Samsung ID is SVE-2019-13899 (April 2019).
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 confidenceOn Samsung mobile devices running Android P (9.0), a vulnerability in the Secure Folder notification handling allows paired smartwatch devices to receive and display Secure Folder notification content that should remain private. The smartwatch acts as an external display channel that bypasses the Secure Folder's intended isolation of sensitive notifications.

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 checksWork through these to decide whether this CVE applies to you.
-
Check Android versionVerify the device is running Android 9.0 (API level 28) by checking system settings or running 'getprop ro.build.version.release'Affected if The Android version equals 9.0 exactly
-
Confirm device manufacturerIdentify if the device is a Samsung device by checking the device model or manufacturer information in system settings or via 'getprop ro.product.brand'Affected if The device is a Samsung-branded device
-
Verify Secure Folder is configuredCheck if Samsung Secure Folder feature is enabled on the device - look for Secure Folder app in the app drawer or check settings under Biometrics and Security > Secure FolderAffected if Secure Folder is present and configured on the device
-
Check for paired smartwatch with notification mirroringCheck if any smartwatch or wearable device is paired via Bluetooth settings, and verify if notification mirroring/receiving notifications from other apps is enabled in the smartwatch companion app settingsAffected if A smartwatch is paired and notification mirroring to the smartwatch is enabled
The device is affected if it is a Samsung device running Android 9.0 with Secure Folder enabled and a paired smartwatch with notification mirroring active.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataOrganizations should ensure Samsung devices with P(9.0) receive the April 2019 security patch (SVE-2019-13899). Until patched, consider disabling notification mirroring to smartwatch devices or restricting smartwatch pairing for users with Sensitive data in Secure Folder.
