Unauthenticated device performance degradation
Published Oct 28, 2021 · Updated Aug 3, 2024
Improper authentication in Huawei EMUI 10.1.0, 10.1.1, and 11.0.0 allows remote attackers to degrade device performance. Huawei identifies only a permission-verification failure and has not disclosed the affected component, the rejected or accepted operation, or the triggering input. No authentication or user interaction is required; the documented consequence is limited to reduced device performance rather than data access or modification.
