CVE-2022-47461

Local privilege escalation via missing telephone authorization

Published Mar 7, 2023 · Updated Mar 5, 2025

Missing authorization in UNISOC chipsets running Android 10 or Android 11 allows local users to gain elevated system access. UNISOC identifies only a missing permission check in the telephone service and does not disclose the affected function or operation. The documented gate is local access with system execution privileges; successful exploitation crosses the telephone-service authorization boundary.
