CVE-2025-32331

Local privilege escalation via dismissible keyguard

Published Sep 4, 2025 · Updated Sep 4, 2025

Protection mechanism failure in Android 15 and 16 allows local users to escape app pinning without user interaction. KeyguardService.showDismissibleKeyguard displays a dismissible keyguard when a foldable closes with “Swipe up to continue” enabled, dropping the pinned app's security state. Exploitation requires low-privileged local access, a pinned app, and the affected foldable setting; successful escape exposes functions outside the pinned app.
