CVE-2024-47294

Local availability loss

Published Sep 27, 2024 · Updated Sep 27, 2024

Access-permission verification in Huawei HarmonyOS and EMUI input method frameworks allows local users to impair availability. Huawei has not disclosed which permission check is incorrect or how input-method data reaches it. The vendor-published vector limits exploitation to local users with high privileges, and the reported consequence is availability loss only; the failure mode is undisclosed.
