CVE-2025-68958 is a concurrency 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 locking or synchronization mechanisms, leading to unpredictable behavior such as data corruption or system instability. The vulnerability specifically affects the availability and integrity of the system, as concurrent execution conflicts can cause crashes or denial of service conditions. The CVSS 3.1 base score of 8.0 reflects a high-severity issue, with an attack vector limited to local access (AV:L), low attack complexity (AC:L), no privileges required (PR:N), and no user interaction needed (UI:N). The scope remains unchanged (S:U), but confidentiality is slightly impacted (C:L), while integrity and availability are highly impacted (I:H, A:H). No patches have been published yet, and no known exploits are reported in the wild, but the vulnerability poses a significant risk to devices running the affected HarmonyOS version. The vulnerability's local attack vector implies that attackers need some form of local access, such as physical access or through compromised local accounts, to exploit the race condition. The card framework module is likely a critical component handling card-related operations, possibly including SIM cards, payment cards, or other secure elements, making the impact on availability and integrity particularly concerning for device functionality and security.

For European organizations, the exploitation of this vulnerability could lead to denial of service conditions on devices running HarmonyOS 6.0.0, potentially disrupting business operations that rely on these devices. The integrity impact suggests possible data corruption or unauthorized modification of card-related data, which could affect secure transactions or authentication processes. Organizations in sectors such as telecommunications, finance, and critical infrastructure that utilize Huawei devices may experience operational interruptions or security breaches. The local attack vector means that insider threats or attackers with physical or local access could exploit the vulnerability, increasing the risk in environments with less stringent access controls. The lack of current exploits reduces immediate risk, but the high CVSS score and nature of the vulnerability warrant proactive mitigation. Additionally, the availability impact could affect user trust and compliance with data protection regulations like GDPR if service disruptions occur.

Since no official patches are currently available, European organizations should implement strict local access controls to prevent unauthorized users from gaining physical or local access to HarmonyOS devices. Employ device-level security measures such as strong authentication, device encryption, and runtime protection mechanisms to detect and prevent race condition exploitation. Monitor Huawei's security advisories closely for patch releases and apply updates promptly once available. Conduct regular security audits and penetration testing focusing on concurrency issues in critical modules. Where possible, segment networks to isolate vulnerable devices and limit exposure. Educate staff about the risks of local exploitation and enforce policies to minimize insider threats. Consider deploying endpoint detection and response (EDR) solutions capable of identifying anomalous behavior indicative of race condition exploitation. Finally, collaborate with Huawei support channels to obtain guidance and early access to fixes.
