CVE-2023-30698

Unauthorized BLE connection via missing access control

Published Aug 10, 2023 · Updated Oct 4, 2024

Improper access control in TelephonyUI on Samsung Mobile Devices running Android 13 allows local users to connect BLE without privilege. TelephonyUI fails to enforce the required access-control check before establishing the BLE connection; Samsung has not disclosed the affected function or request path. A low-privileged local user can therefore establish an unauthorized BLE connection, while the published record reports no confidentiality impact or code execution.
