CVE-2022-47468

Local telecom-service crash via missing permission check

Published Apr 11, 2023 · Updated Feb 10, 2025

NULL pointer dereference in UNISOC telecom service on affected Android 10 and Android 11 chipsets allows local users to crash the service. UNISOC identifies the locus only as telecom service and states that it omits a permission check; no function, request type, or pointer operation is public. Low-privileged local access is required, and the published impact is limited to loss of telecom-service availability.
