CVE-2025-48597

Local privilege escalation via premature overlay trust

Published Dec 8, 2025 · Updated Feb 26, 2026

Improper UI-layer restriction in the Android Framework on Android 14 through 16 allows local users to elevate privileges via an overlay. WindowManager granted TRUSTED_OVERLAY from a pinned-state notification before WMShell confirmed a successful picture-in-picture transition. A low-privileged app can reach the flaw without user interaction and obtain permissions that the device owner did not approve.
