Unauthenticated data disclosure via out-of-bounds read
Published Jan 3, 2022 · Updated Aug 4, 2024
An out-of-bounds read in Huawei smartphone software allows remote attackers to disclose service data over a network. Huawei identifies affected releases as EMUI 10.1.0, Magic UI 3.1.0, and HarmonyOS 2.0, but has not disclosed the affected component, the input that crosses its bounds, or whether the read exposes process memory directly or only through a response. No authentication or user interaction is required; the published impact is limited to confidentiality, with no integrity or availability effect.
