CVE-2025-48639

Local privilege escalation via transition tapjacking

Published Dec 8, 2025 · Updated Feb 26, 2026

Tapjacking in Android Framework 13 through 16 allows local users to gain privileges by obscuring permission-granting UI. DefaultTransitionHandler permits three-second default transitions while InputDispatcher lets nominally opaque windows below 0.5 alpha receive touches, enabling an overlay to redirect a user's tap. A malicious app and user interaction are required; a successful tap grants app permissions and elevates the app's privileges.
