What to do
AI-suggested
To mitigate this vulnerability, European organizations should prioritize updating affected Samsung Galaxy Watch devices to the SMR August 2025 Release 1 or later, where the access control issue has been addressed. Until patches are applied, organizations should enforce strict physical security controls to limit local access to devices, including secure storage and restricted device handling policies. Additionally, organizations should audit installed applications on these devices to ensure no unauthorized or potentially malicious apps are present that could exploit local access to sensor data. Implementing endpoint management solutions that monitor device configurations and enforce security policies can help detect and prevent exploitation attempts. For environments where sensitive health data is collected, consider encrypting data at rest and in transit and applying strict access controls at the application and network levels. User awareness training on the risks of local device access and the importance of device security can further reduce the risk of exploitation. Finally, organizations should monitor Samsung security advisories for any updates or additional patches related to this vulnerability.
Description
Improper access control in SemSensorManager for Galaxy Watch prior to SMR Aug-2025 Release 1 allows local attackers to access sensitive information related to outdoor exercise and sleep time.
