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 confidenceS-Voice (Samsung's voice assistant) on mobile devices with Android N (7.x) and O (8.x) improperly exposes keyboard learned words through the lock screen interface, allowing unauthorized users to view sensitive data that users have typed and the keyboard has learned.

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 versionGo to Settings > About Phone > Android version. Alternatively, run 'getprop ro.build.version.release' in ADB shell or check the system settings UI.Affected if The Android version is 7.0, 7.1.0, 7.1.1, 7.1.2, 8.0, or 8.1
-
Verify S-Voice app presenceCheck if the S-Voice application is installed on the device. This can be done by looking in the app drawer for S-Voice, or by running 'pm list packages | grep svoice' in ADB shell.Affected if S-Voice is installed on the device
-
Confirm lock screen access to learned keyboard dataFrom the lock screen, attempt to invoke S-Voice (typically by pressing and holding the home button or using a voice wake command if configured). Then try to access any learned words, predicted text, or keyboard data through the S-Voice interface while the device remains locked.Affected if S-Voice is accessible from the lock screen and exposes learned keyboard words or typed data to an unauthorized user
A user is affected if their device runs Android 7.0-8.1, has S-Voice installed, and S-Voice can be accessed from the lock screen to reveal learned keyboard data.

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 dataApply the vendor-supplied Samsung security update (SVE-2018-12981) to affected devices to patch the S-Voice application and prevent lock screen leakage of learned keyboard data.
