CVE-2025-54621

Memory-release failure via WantAgent iterator error

Published Aug 6, 2025 · Updated Aug 6, 2025

Resource-lifetime error in Huawei HarmonyOS 5.1.0 allows local users to trigger memory-release failures in the WantAgent module. The WantAgent iterator fails during resource-lifetime handling, but Huawei has not published the affected code path or incorrect input operation. Low-privileged local access is required; the documented consequence is limited to memory-release failure, and NVD identifies availability impact only.
