CVE-2023-44112Network attack vector

Service-data disclosure via out-of-bounds authentication access

Published Jan 16, 2024 · Updated Sep 3, 2024

Out-of-bounds access in Huawei HarmonyOS and EMUI device authentication modules allows remote attackers to read service data. Huawei identifies the affected module but does not disclose the flawed operation, attacker-controlled input, or memory boundary involved. Network access without authentication or user interaction is sufficient, and the documented consequence is limited to service-data confidentiality.
