CVE-2025-68957 is a concurrency-related vulnerability classified under CWE-362, indicating a race condition due to improper synchronization in Huawei HarmonyOS's card framework module version 6.0.0. The flaw occurs when multiple threads access shared resources without adequate synchronization mechanisms, leading to unpredictable behavior that can be exploited to disrupt system availability. The vulnerability's CVSS v3.1 score is 8.4, reflecting high severity, with vector metrics AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H. This means the attack requires local access (AV:L), low attack complexity (AC:L), no privileges (PR:N), no user interaction (UI:N), unchanged scope (S:U), and impacts confidentiality, integrity, and availability at a high level. Although no public exploits are known, the vulnerability could allow attackers to cause denial of service or potentially escalate to data corruption or leakage by manipulating the card framework's concurrent operations. The card framework is a critical component managing card-related functionalities, and its disruption can affect device stability and security. The vulnerability was reserved on 2025-12-27 and published on 2026-01-14, with no patches currently linked, indicating that mitigation may require vendor updates or workarounds. Given the local attack vector, attackers need access to the device, which may limit exposure but still poses a significant risk in environments where devices are shared or physically accessible.

For European organizations, the primary impact of CVE-2025-68957 lies in potential service disruption due to availability degradation of devices running HarmonyOS 6.0.0. This can affect operational continuity, especially in sectors relying on Huawei hardware for critical communications or IoT deployments. The high confidentiality and integrity impact ratings suggest that beyond availability, sensitive data could be exposed or altered if attackers exploit the race condition to manipulate the card framework's operations. This is particularly concerning for industries handling personal data or critical infrastructure. The requirement for local access reduces remote exploitation risk but does not eliminate insider threats or risks from compromised endpoints. Disruptions could cascade in interconnected systems, affecting broader organizational IT and operational technology environments. The lack of patches at present increases the window of exposure, necessitating proactive risk management. Additionally, organizations using Huawei devices in multi-user or shared environments face elevated risks of exploitation due to easier local access.

1. Monitor Huawei's security advisories closely and apply official patches or updates for HarmonyOS 6.0.0 as soon as they become available to address this race condition vulnerability. 2. Implement strict physical and logical access controls to limit local access to devices running HarmonyOS, reducing the risk of local exploitation. 3. Employ endpoint detection and response (EDR) solutions to detect anomalous behaviors related to the card framework or concurrent execution anomalies. 4. Where possible, isolate critical Huawei devices from untrusted users or networks to minimize attack surface. 5. Conduct regular security audits and penetration testing focusing on concurrency and synchronization issues within deployed Huawei devices. 6. Educate users and administrators about the risks of local exploitation and enforce policies to prevent unauthorized device access. 7. Consider deploying runtime application self-protection (RASP) or similar technologies that can detect and mitigate race condition exploitation attempts. 8. If patching is delayed, explore temporary workarounds such as disabling or restricting the card framework module functionalities if feasible without disrupting essential services.
