CVE-2022-47463

Local service interruption via missing permission check

Published Apr 11, 2023 · Updated Feb 10, 2025

Buffer overflow in the telecom service on UNISOC chipsets running Android 10 through Android 13 allows local users to interrupt the service. UNISOC identifies a missing permission check and classic buffer overflow but does not disclose the affected function, buffer, or attacker-controlled input. Low-privileged local access is required, no user interaction is needed, and public records do not specify whether denial of service occurs through a crash, hang, or another interruption mode.
