CVE-2022-47480

Local telephone-service crash via missing permission check

Published Mar 7, 2023 · Updated Mar 5, 2025

Missing authorization in UNISOC Android 10 telephony service allows local users to crash and interrupt telephone service. The service omits a permission check before processing a local telephony request, permitting an unauthorized path to reach a null-pointer dereference. A local process needs no additional execution privileges or user interaction; the documented consequence is loss of telephone-service availability.
