Technical Details for CVE-2025-68967
Vulnerability Analysis
This vulnerability stems from improper permission control within the print module of HarmonyOS. The print module fails to properly validate and enforce access permissions, creating an avenue for unauthorized information disclosure. The attack requires local access to the device with low-level privileges, and no user interaction is needed for exploitation.
The vulnerability is classified under CWE-264 (Permissions, Privileges, and Access Controls), indicating fundamental issues with how the print module manages access rights. When exploited, an attacker could gain access to confidential information that should be restricted, though the flaw does not allow modification of data or disruption of system availability.
Root Cause
The root cause of CVE-2025-68967 lies in insufficient permission validation within the HarmonyOS print module. The module does not properly verify that requesting processes have appropriate authorization before granting access to print-related data and functionality. This allows processes with minimal privileges to access information that should require elevated permissions.
Attack Vector
The attack vector for this vulnerability is local, meaning an attacker must already have some level of access to the target HarmonyOS device. The exploitation requires only low privileges and no user interaction, making it relatively straightforward for an attacker who has established a foothold on the device.
The attacker would need to interact with the print module through local system calls or application interfaces. By leveraging the improper permission controls, the attacker can bypass intended access restrictions and retrieve confidential data processed or stored by the print module. This could include print job contents, queued documents, or configuration information.
Detection Methods for CVE-2025-68967
Indicators of Compromise
- Unusual access patterns to print module services or data stores by low-privileged processes
- Unexpected print-related API calls from applications that do not typically use printing functionality
- Anomalous permission requests or access attempts logged in system security logs
Detection Strategies
- Monitor system calls and IPC communications involving the print module for unauthorized access attempts
- Implement application behavior analysis to detect processes accessing print functionality outside their normal scope
- Review system audit logs for permission-related errors or unexpected access grants in the print subsystem
Monitoring Recommendations
- Enable comprehensive logging for print module activities and permission checks
- Deploy endpoint detection and response (EDR) solutions capable of monitoring HarmonyOS system behavior
- Establish baseline behavior for print module access and alert on deviations
How to Mitigate CVE-2025-68967
Immediate Actions Required
- Update HarmonyOS to the latest patched version as provided by Huawei
- Review and restrict application permissions, particularly for apps that do not require print functionality
- Monitor devices for signs of exploitation while awaiting patch deployment
Patch Information
Huawei has addressed this vulnerability in their January 2026 security bulletin. Administrators should consult the Huawei Security Bulletin 2026 for detailed patch information. For laptop devices running HarmonyOS, refer to the Huawei Laptop Security Bulletin 2026.
Apply the security updates through the standard HarmonyOS update mechanism or by following Huawei's official update procedures.
Workarounds
- Restrict physical and remote access to HarmonyOS devices to trusted users only
- Disable or limit print module functionality if not required for business operations
- Implement application allowlisting to prevent unauthorized applications from running on affected devices
- Use mobile device management (MDM) solutions to enforce security policies and monitor device compliance
