CVE-2021-22454

Local service crash via undisclosed configuration control

Published Oct 28, 2021 · Updated Aug 3, 2024

External control of a system setting in Huawei HarmonyOS 2.0 allows local users to trigger a core dump and interrupt service. Huawei identifies only an unspecified HarmonyOS component and does not disclose which setting accepts attacker-controlled data or how it is applied. Reachability requires local low-privilege access, and the documented consequence is limited to the affected service or component crashing.
