Published Dec 20, 2022 · Updated Apr 16, 2025
Out-of-bounds memory write in Huawei HarmonyOS 2.0 and EMUI 12.0.0 allows remote attackers to trigger system service exceptions. Huawei has not disclosed the affected component, input path, or boundary-checking operation that permits the write beyond its intended buffer. The published assessment requires no privileges or user interaction; public material bounds the reported consequence to abnormal system services.
