CVE-2022-48296Network attack vector

False storage alerts via unauthorized broadcasts

Published Feb 9, 2023 · Updated Mar 25, 2025

Improper permission management in Huawei SystemUI on affected HarmonyOS and EMUI releases allows attackers to display false storage alerts. SystemUI accepts storage-related broadcasts from malicious apps without preserving the intended permission boundary, but Huawei has not disclosed the affected API or validation logic. A malicious app must execute on the device; the demonstrated consequence is deceptive external-storage warning information, not data access or service interruption.
