CVE-2025-68956

8.0

Huawei · HarmonyOS

A multi-thread race condition exists in the HarmonyOS card framework module, which may lead to unauthorized data modification or system instability.

Executive summary

A race condition vulnerability in the Huawei HarmonyOS card framework poses a significant risk to system integrity and availability.

Vulnerability

The flaw is a race condition (CWE-362) occurring within the card framework module due to improper synchronization during concurrent execution. An unauthenticated local attacker can exploit this condition to achieve high integrity and availability impacts.

Business impact

The vulnerability carries a CVSS score of 8.0, reflecting its potential to severely impact system operations. Successful exploitation could lead to unauthorized data modification or denial of service, potentially disrupting critical device functions and compromising the reliability of the affected Huawei ecosystem.

Remediation

Immediate Action: Organizations and users should monitor the official Huawei security portal for the release of firmware updates addressing this race condition and apply them immediately upon availability.

Proactive Monitoring: Security teams should monitor system logs for unusual process behavior or unexpected service restarts that may indicate attempted exploitation of the card framework.

Compensating Controls: Given the local nature of the attack vector, enforce strict physical security and limit unauthorized access to the device to prevent potential attackers from reaching the vulnerable interface.

Exploitation status

Public Exploit Available: No (exploit_available: false)

Analyst recommendation

This vulnerability presents a high-severity risk to HarmonyOS environments due to the potential for significant integrity and availability loss. Users are strongly advised to prioritize firmware updates as soon as Huawei provides a patch, as the nature of race condition flaws often allows for reliable exploitation once a technical method is identified.
