CVE-2022-47477

Local information disclosure via missing telephony authorization

Published Mar 7, 2023 · Updated Mar 6, 2025

Missing authorization in the telephony service on UNISOC chipsets running Android 10 or Android 11 allows local users to disclose protected data. The service omits a required permission check before exposing information, but the affected entry point and disclosed data remain unpublished. A local low-privileged user can reach the flaw without user interaction; the documented consequence is confidentiality loss only.
