Data disclosure and service interruption via unchecked input
Published Feb 18, 2024 · Updated Nov 21, 2024
Input-validation failure in Huawei EMUI and HarmonyOS allows remote attackers to read data or interrupt service through the cellular data module. The module fails to validate input before a buffer operation, but Huawei has not disclosed the affected function, input field, or access path. Exploitation is unauthenticated and network-reachable but requires high attack complexity; the documented effects are confidentiality loss and service interruption.
