CVE-2026-24916 identifies a security vulnerability in Huawei's HarmonyOS 6.0.0, specifically within the window module responsible for identity authentication. This vulnerability allows an attacker to bypass authentication mechanisms, leading to unauthorized access to sensitive information, thereby compromising service confidentiality. The vulnerability is classified under CWE-200, which pertains to the exposure of sensitive information to unauthorized actors. The CVSS 3.1 base score is 5.9, indicating a medium severity level. The vector string (AV:P/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N) reveals that the attack requires physical access (AV:P), low attack complexity (AC:L), no privileges (PR:N), and user interaction (UI:R). The scope is unchanged (S:U), with high impact on confidentiality (C:H) and integrity (I:H), but no impact on availability (A:N). No patches or known exploits are currently available, and the vulnerability was published on February 6, 2026. The lack of known exploits suggests it is not yet actively targeted, but the potential for sensitive data exposure warrants proactive mitigation. The window module's role in identity authentication means that bypassing it could allow attackers to impersonate legitimate users or access restricted data, posing significant risks to affected systems.

For European organizations, the primary impact of CVE-2026-24916 is the potential unauthorized disclosure of sensitive information due to authentication bypass in Huawei HarmonyOS devices. This could affect confidentiality and integrity of data, particularly in sectors handling personal data, intellectual property, or critical infrastructure information. Organizations relying on Huawei devices running HarmonyOS 6.0.0 may face increased risks of data breaches or espionage. Since the attack vector requires physical access and user interaction, the threat is more pronounced in environments where devices are accessible to untrusted individuals or users might be socially engineered. The absence of availability impact reduces the risk of service disruption but does not mitigate the confidentiality and integrity concerns. European entities with Huawei-based IoT deployments, mobile devices, or embedded systems could be vulnerable, potentially leading to regulatory compliance issues under GDPR if personal data is exposed. The medium severity suggests a moderate risk level, but the strategic importance of Huawei technology in Europe, combined with geopolitical tensions, could elevate the threat profile for certain sectors.

1. Monitor Huawei's official channels for security advisories and promptly apply patches once available. 2. Restrict physical access to devices running HarmonyOS 6.0.0, especially in sensitive environments, to reduce the risk of exploitation requiring physical proximity. 3. Educate users about the risks of social engineering and the importance of cautious interaction with device prompts to minimize user interaction exploitation. 4. Implement network segmentation and strict access controls to limit exposure of Huawei devices to untrusted networks or users. 5. Employ endpoint detection and response (EDR) solutions capable of monitoring unusual authentication bypass attempts or suspicious activity on HarmonyOS devices. 6. Conduct regular security audits and vulnerability assessments focusing on Huawei device deployments. 7. Consider alternative devices or operating systems for critical applications where feasible, to reduce dependency on potentially vulnerable platforms. 8. Maintain robust incident response plans tailored to potential data exposure incidents involving Huawei devices.
