CVE-2022-44554 is a high-severity vulnerability identified in Huawei's HarmonyOS version 2.0, specifically within the power management module. The vulnerability arises from improper permission verification (classified under CWE-276: Incorrect Default Permissions), which allows an unauthenticated remote attacker to exploit the flaw without any user interaction. The CVSS 3.1 base score is 7.5, indicating a high impact primarily on availability (CVSS vector: AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H). Successful exploitation can cause abnormal behavior or disruption of the power module on affected devices, potentially leading to denial of service conditions or instability in device operation. Since the vulnerability does not impact confidentiality or integrity, the main risk is service disruption. No known exploits have been reported in the wild, and no official patches or mitigation links are currently published by Huawei. The vulnerability's network attack vector and lack of required privileges make it a significant risk for devices running HarmonyOS 2.0, especially those exposed to untrusted networks.

For European organizations, the impact of CVE-2022-44554 could be substantial in environments where Huawei HarmonyOS devices are deployed, such as in mobile devices, IoT endpoints, or embedded systems. Disruption of the power module could lead to device instability or outages, affecting business continuity, especially in critical infrastructure or industrial control systems using HarmonyOS-based devices. Although the vulnerability does not compromise data confidentiality or integrity, availability issues could interrupt operations, cause loss of productivity, or degrade user experience. Organizations relying on Huawei devices for communication or operational technology should be aware of potential service disruptions. The absence of known exploits reduces immediate risk, but the ease of exploitation and network accessibility necessitate proactive risk management.

Given the lack of official patches, European organizations should implement network-level protections such as strict firewall rules to limit exposure of HarmonyOS devices to untrusted networks. Employ network segmentation to isolate vulnerable devices and monitor network traffic for anomalous activity targeting power management interfaces. Device hardening by disabling unnecessary services and restricting device management interfaces can reduce attack surface. Organizations should maintain up-to-date inventories of Huawei HarmonyOS devices and track vendor advisories for forthcoming patches. Incident response plans should include procedures for detecting and mitigating abnormal device behavior indicative of exploitation attempts. Additionally, consider deploying endpoint detection and response (EDR) solutions capable of monitoring device health and power module anomalies.
