CVE-2022-28777

Unauthorized calls via missing CALL_PHONE permission check

Published Apr 11, 2022 · Updated Aug 3, 2024

Improper access control in Samsung Members before 13.6.08.5 allows local users to place calls without the CALL_PHONE permission. Samsung has not identified the affected component or published implementation details, but confirms that the call function fails to enforce the Android CALL_PHONE permission. Local code execution on a Galaxy phone or tablet is required, and the bounded consequence is unauthorized telephone-call initiation rather than broader device control.
