CVE-2021-25523

Account identifier disclosure via insecure device-information storage

Published Dec 8, 2021 · Updated Aug 3, 2024

Information disclosure in Samsung Phone before 12.7.05.24 allows local users to obtain the device's Samsung Account ID. Samsung identifies insecure storage of device information in the Dialer but has not disclosed the storage location or missing protection that exposes the identifier. Local execution on an Android 11 device with a signed-in Samsung Account is required, and the documented impact is limited to disclosure of that account identifier.
