CVE-2022-48444

Local telephony-service crash via null pointer dereference

Published Jun 6, 2023 · Updated Jan 7, 2025

NULL pointer dereference in UNISOC chipsets running Android 10 through 12 allows local users to interrupt the telephony service. A missing permission check permits an unprivileged local caller to reach a telephony-service path that dereferences a null pointer; UNISOC has not identified the affected function or request. No additional execution privileges or user interaction are required, and the reported consequence is limited to a local service crash.
