CVE-2025-68960: Huawei HarmonyOS Race Condition Vulnerability

CVE-2025-68960 Overview

CVE-2025-68960 is a multi-thread race condition vulnerability affecting the video framework module in Huawei HarmonyOS. This race condition flaw occurs when multiple threads attempt to access shared resources within the video processing subsystem without proper synchronization, potentially leading to system instability and denial of service conditions.

Critical Impact
Successful exploitation of this vulnerability may affect system availability, causing video framework crashes or device instability on affected HarmonyOS devices.

Technical Details for CVE-2025-68960

Vulnerability Analysis

This vulnerability is classified as CWE-362 (Concurrent Execution using Shared Resource with Improper Synchronization), commonly known as a race condition. The flaw exists within the video framework module of HarmonyOS, where multi-threaded operations on shared video processing resources lack proper synchronization mechanisms.

Race conditions in multimedia frameworks are particularly concerning because video processing typically involves multiple concurrent threads handling tasks such as decoding, rendering, and buffer management. When these threads compete for shared resources without adequate locking or synchronization primitives, the system can enter an inconsistent state.

The vulnerability requires local access to the device and has high attack complexity due to the timing-dependent nature of race conditions. An attacker with low-level privileges must carefully time their exploitation attempts to trigger the race condition window. While the vulnerability does not compromise data confidentiality or integrity, successful exploitation results in high availability impact, potentially causing the video framework to crash or become unresponsive.

Root Cause

The root cause stems from improper synchronization in the video framework module when handling concurrent thread operations. Specifically, the vulnerability is a Time-of-Check Time-of-Use (TOCTOU) style race condition where the state of a shared resource can change between the time it is checked and the time it is used by another thread. This occurs because critical sections of code that access shared video processing resources lack proper mutex locks, semaphores, or other synchronization mechanisms to ensure atomic operations.

Attack Vector

The attack vector is local, requiring an attacker to have some level of access to the affected HarmonyOS device. Exploitation involves triggering specific video processing operations that cause multiple threads to compete for the same resources simultaneously. Due to the high complexity required to consistently trigger the race condition, the attacker must:

Identify the specific timing window where the race condition can be exploited
Execute operations that cause concurrent access to the vulnerable shared resources in the video framework
Repeatedly attempt exploitation until the race condition window is successfully hit

The vulnerability primarily affects system availability rather than data security, making it suitable for denial of service attacks against the video subsystem.

Detection Methods for CVE-2025-68960

Indicators of Compromise

Unexpected video framework crashes or service restarts on HarmonyOS devices
System logs showing abnormal thread termination or synchronization errors in video processing components
Repeated application crashes when video playback or recording functions are used
High CPU utilization spikes associated with video framework processes

Detection Strategies

Monitor system logs for race condition-related errors such as deadlocks, thread crashes, or synchronization failures in the video framework module
Implement application performance monitoring to detect anomalous video processing behavior
Deploy endpoint detection solutions capable of identifying denial of service patterns targeting multimedia subsystems
Review crash dumps for evidence of concurrent access violations in video framework components

Monitoring Recommendations

Enable verbose logging for the HarmonyOS video framework module to capture thread synchronization events
Implement automated alerting for repeated video service crashes that may indicate exploitation attempts
Monitor device stability metrics across the HarmonyOS fleet to identify patterns consistent with race condition exploitation
Utilize SentinelOne's behavioral analysis capabilities to detect anomalous process behavior associated with video framework manipulation

How to Mitigate CVE-2025-68960

Immediate Actions Required

Apply the latest HarmonyOS security updates as outlined in the Huawei Security Bulletin for January 2026
For laptop devices, review the Huawei Laptop Security Bulletin for January 2026
Ensure all HarmonyOS devices running versions 5.0.1 and 5.1.0 are prioritized for patching
Restrict physical and local access to affected devices until patches can be applied

Patch Information

Huawei has released security patches addressing this vulnerability in their January 2026 security bulletin. Organizations and users should update their HarmonyOS devices to the latest available version that includes the fix for CVE-2025-68960. The patches address the synchronization issues in the video framework module by implementing proper locking mechanisms for shared resource access.

Refer to the official Huawei security advisories for detailed patch information:

Workarounds

Limit video playback and recording functionality on affected devices in high-security environments until patches are applied
Restrict local access to devices to trusted users only, reducing the attack surface for local exploitation
Monitor affected devices for signs of instability and isolate any systems showing symptoms of exploitation
Consider disabling non-essential video processing features temporarily if operational requirements allow
