CVE-2024-31324

Local privilege escalation via stale overlay visibility

Published Jul 9, 2024 · Updated Mar 15, 2025

Tapjacking protection bypass in Android 12, 12L, 13, and 14 allows local users to escalate privileges through screen rotation. WindowState.hide incorrectly waits for a parent container's animation callback when the window has no hide animation, leaving a policy-hidden window visible. Exploitation requires user execution privileges, a portrait-first activity rotated to landscape, and user interaction; successful tapjacking bypasses overlay protection to elevate privileges.
