CVE-2020-1835

Information disclosure via Bluetooth logic judgment error

Published Jun 18, 2020 · Updated Aug 4, 2024

Information disclosure in Huawei Mate 30 before 10.1.0.126(C00E125R5P3) allows attackers to disclose information over Bluetooth. The Bluetooth connection handler makes an incorrect logic decision when a crafted peer presents as authenticated. Exploitation requires Bluetooth proximity, a crafted authenticated-peer interaction, and user interaction; the published impact is limited to information disclosure.
