Some Huawei mobile phone with the versions before BLA-L29 8.0.0.145(C432) have a denial of service (DoS) vulnerability because they do not adapt to specific screen gestures. An attacker may trick users into installing a malicious app. As a result, apps running on the frontend crash after the users make specific screen gestures.
