Memory disclosure and service interruption via out-of-bounds read
Published Dec 8, 2021 · Updated Aug 4, 2024
Out-of-bounds read in Huawei EMUI 10.1.1 and 11.0.0 and HarmonyOS 2.0 allows remote attackers to read beyond a memory buffer. Huawei has not published the affected component, input path, or operation that reads beyond the buffer boundary. Network access requires neither authentication nor user interaction; exploitation can expose memory contents or interrupt phone services.
