CVE-2022-39008

System-app file access via mismatched bundle deserialization

Published Sep 16, 2022 · Updated Jun 3, 2025

NFC bundle deserialization mismatch in Huawei EMUI 12.0.0 and HarmonyOS 2.0 allows attackers to read and write system-app files via third-party apps. The NFC module serializes and deserializes bundle data inconsistently, permitting a third-party app to cross system-app file-access boundaries. A third-party app must reach the affected module; exploitation exposes and modifies files otherwise restricted to system apps.
