CVE-2023-34154Network attack vector

Resource exhaustion via arbitrary window creation

Published Jun 16, 2023 · Updated Dec 17, 2024

Incorrect permission assignment in Huawei HarmonyOS 2.0.0 and 3.0.0 allows remote attackers to consume system resources via HUAWEI VR screen projection. The VR screen projection permission handling lets third-party applications create windows without intended authorization, consuming system resources. Attackers able to trigger this behavior can exhaust resources and interrupt service; the record reports no confidentiality impact.
