CVE-2023-52342Network attack vector

Remote information disclosure via unchecked modem error

Published Apr 8, 2024 · Updated Mar 13, 2025

Information disclosure in modem-ps-nas-ngmm in UNISOC T760, T770, T820, and S8000 firmware allows remote attackers to expose data. The modem component handles an error incorrectly and proceeds into undefined behavior; UNISOC has not disclosed the failing operation or triggering network input. No privileges or user interaction are required, but the vendor's CVSS vector records only low availability impact and no confidentiality impact.
