CVE-2026-0046

Local privilege escalation via trusted letterbox touches

Published Jun 1, 2026 · Updated Jun 1, 2026

Tapjacking in Android 14 through 16 allows local users to obtain unauthorized permissions through touches sent via a hidden letterbox region. InputInterceptor in Letterbox.java treats the letterbox window as trusted, so touches that slip outside its black bar reach a covered activity without triggering overlay protections. No execution privileges or user interaction are required, and the demonstrated consequence is unauthorized permission acceptance rather than arbitrary code execution.
