CVE-2024-27897Network attack vector

Unauthenticated service-data disclosure through call module

Published Apr 8, 2024 · Updated Aug 2, 2024

Input verification failure in Huawei EMUI and HarmonyOS allows remote attackers to read confidential service data through the call module. Huawei identifies the call module but has not published the input field, validation error, request format, or code path that exposes the data. The published CISA assessment treats exploitation as network-reachable and unauthenticated, with confidentiality impact only and no reported ability to modify data or interrupt service.
