CVE-2026-0046
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 · uneditedIn InputInterceptor of Letterbox.java, there is a possible way to trick a user into accepting a permission due to a tapjacking/overlay attack. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.
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 confidenceThis is a tapjacking/overlay vulnerability in Android's Letterbox InputInterceptor component. Attackers can exploit this to intercept user inputs and trick the system into granting permissions or performing privileged actions through malicious overlay attacks. The vulnerability allows local privilege escalation without requiring user interaction.

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 and verify the Android version numberAffected if The Android version is exactly 14.0, 15.0, or 16.0
-
Review apps with overlay permissionNavigate to Settings > Apps > Special app access > Apps that can appear on top and list all applications granted this permissionAffected if Any untrusted or suspicious application has the SYSTEM_ALERT_WINDOW (overlay) permission granted
-
Identify letterboxed apps in useCheck which applications are running in letterbox (compatibility) mode on the device - this mode is used for displaying apps in a letterboxed view on devices with different aspect ratiosAffected if Applications are running in letterbox mode on an affected Android version (14.0-16.0)
-
Audit recently installed appsReview the list of recently installed applications, particularly those requesting overlay or accessibility permissionsAffected if Recently installed apps with overlay permissions exist alongside an affected Android version
A device is affected if it runs Android 14.0, 15.0, or 16.0 AND has any untrusted applications granted overlay (SYSTEM_ALERT_WINDOW) permission, since the tapjacking vulnerability in InputInterceptor could be exploited to intercept user input in letterboxed apps.

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 Android security patches for CVE-2026-0046. Developers should implement overlay detection mechanisms and ensure InputInterceptor properly validates input sources before processing, particularly in Letterbox/multi-window modes.
