CVE-2023-44100Network attack vector

Service confidentiality impact via Bluetooth broadcast permissions

Published Oct 11, 2023 · Updated Sep 18, 2024

Permission control in the Bluetooth module in Huawei HarmonyOS 2.0.0 through 4.0.0 allows remote attackers to access service data via broadcast notifications. The same issue affects Huawei EMUI 11.0.1 through 13.0.0. Huawei has not disclosed the specific permission-check locus or the exact data exposed; exploitation requires Bluetooth reachability and results in confidentiality impact without a reported integrity or availability effect.
