CVE-2021-40061Network attack vector

Unauthorized system-state modification via Bastet type confusion

Published Mar 7, 2022 · Updated Aug 4, 2024

Type confusion in Huawei's Bastet module allows remote attackers to alter system state in affected HarmonyOS, EMUI, and Magic UI releases. The module accesses a resource through an incompatible type, but Huawei has not published the affected function, input path, or resulting write operation. Affected releases are HarmonyOS 2.0; EMUI 10.1.0, 10.1.1, 11.0.0, 11.0.1, and 12.0.0; and Magic UI 3.1.0, 3.1.1, and 4.0.0; NVD assesses network reachability without authentication or user interaction, while the public record identifies only integrity impact.
