CVE-2022-33733

Local Bluetooth connection disclosure via unprotected callback

Published Aug 5, 2022 · Updated Aug 3, 2024

Sensitive information exposure in Samsung Charm before 1.2.3 allows local users to read Bluetooth connection information without permission. The onCharacteristicRead callback exposes those details without enforcing an access permission on the requesting local process. Exploitation requires local access to the paired-device environment; the reported consequence is disclosure only, with no integrity or availability impact.
