System reset via out-of-bounds memory write
Published Aug 2, 2021 · Updated Aug 3, 2024
Out-of-bounds memory write in EMUI 8.0, 8.2, 9.1.0, and 10.0.0 allows remote attackers to reset affected phones. Huawei has not published the affected component, input path, or operation that writes beyond its intended memory boundary. Exploitation requires network access but no privileges or user interaction, and the documented consequence is a system reset rather than code execution.
