Published Aug 6, 2025 · Updated Aug 6, 2025

Improper access control in Galaxy Watch Android Watch 16 allows local users to read outdoor-exercise and sleep-time data via SemSensorManager. SemSensorManager returns this sensor-derived activity information without proper access control; Samsung has not disclosed the affected interface or missing check. A local execution context on an affected watch is required, and the reported impact is limited to disclosure of those activity and sleep details.
