CVE-2025-20912

Local data disclosure via incorrect default permissions

Published Mar 6, 2025 · Updated Mar 6, 2025

Incorrect default permissions in DiagMonAgent in Samsung Mobile Devices on Android Watch 14 allow local users to read Galaxy Watch data. DiagMonAgent grants overly broad default access instead of enforcing the component's intended access controls on stored watch data. Exploitation requires local code execution on an affected watch, needs no additional privileges or user interaction, and affects confidentiality only.
