CVE-2025-68955 is a concurrency-related vulnerability classified under CWE-362, indicating a race condition due to improper synchronization in the card framework module of Huawei's HarmonyOS version 6.0.0. This flaw occurs when multiple threads access shared resources without adequate synchronization mechanisms, leading to unpredictable behavior such as data corruption, inconsistent state, or system crashes. The vulnerability specifically impacts the availability of the system and also poses risks to confidentiality and integrity, as indicated by the CVSS vector (C:L/I:H/A:H). The attack vector is local (AV:L), meaning an attacker needs local access to the device, but no privileges (PR:N) or user interaction (UI:N) are required, which lowers the barrier for exploitation once local access is obtained. The vulnerability was reserved on 2025-12-27 and published on 2026-01-14, with no known exploits in the wild to date. The lack of available patches at the time of reporting means affected users must rely on interim mitigations. The race condition in the card framework module suggests that critical operations related to card management (e.g., SIM cards, payment cards, or access cards) could be disrupted, potentially causing denial of service or data integrity issues. Given Huawei's significant presence in mobile and IoT devices running HarmonyOS, this vulnerability could have broad implications for device stability and security.

For European organizations, the impact of CVE-2025-68955 could be substantial, particularly for those relying on Huawei HarmonyOS devices in critical infrastructure, telecommunications, or enterprise environments. The vulnerability can lead to denial of service conditions, disrupting business operations and potentially causing data loss or corruption. The confidentiality and integrity impacts suggest that sensitive information handled by the card framework could be exposed or altered, raising compliance and privacy concerns under regulations like GDPR. The local attack vector means that physical or local network access is required, which somewhat limits remote exploitation but does not eliminate insider threats or attacks via compromised local devices. Organizations using Huawei devices for secure transactions or identity management may face increased risk of operational disruption and data breaches. The absence of known exploits currently provides a window for proactive mitigation, but the high CVSS score indicates that once exploited, the consequences could be severe.

1. Monitor Huawei’s official security advisories closely and apply patches promptly once released to address CVE-2025-68955. 2. Implement strict access controls to limit local access to devices running HarmonyOS, including physical security measures and network segmentation to reduce the attack surface. 3. Employ runtime application self-protection (RASP) or endpoint detection and response (EDR) solutions capable of detecting anomalous thread behavior or race condition exploitation attempts. 4. Conduct code audits and concurrency testing for custom applications interacting with the card framework to identify and remediate synchronization issues. 5. Enforce strict privilege separation and sandboxing on HarmonyOS devices to minimize the impact of local exploits. 6. Educate staff about the risks of local device compromise and enforce policies to prevent unauthorized device access. 7. Consider deploying additional monitoring for system stability and integrity indicators that could signal exploitation attempts. 8. For critical environments, evaluate the risk of continued use of affected HarmonyOS versions and consider alternative platforms until patches are available.
