CVE-2019-20599Network attack vector

Secured-app notification sounds via audibility mishandling

Published Mar 24, 2020 · Updated Aug 5, 2024

Authorization flaw in Samsung Voice Assistant on Android 7.x, 8.x, and 9.0 allows attackers to make secured-app notifications audible. The component applies an incorrect audibility state to secured-app notifications; the public record does not disclose the responsible function, input, or authorization check. The condition concerns notifications from a secured app, and the only documented consequence is unintended sound rather than data access or code execution.
