CVE-2025-68965 Overview
CVE-2025-68965 is a permission control vulnerability affecting the Notepad module in Huawei HarmonyOS. This flaw stems from improper access control mechanisms that fail to adequately restrict access to sensitive data within the Notepad application. Successful exploitation of this vulnerability may compromise service confidentiality, potentially allowing unauthorized local users to access sensitive information stored within the Notepad module.
Critical Impact
Local attackers with low privileges can exploit this permission control flaw to gain unauthorized access to confidential data stored in the Notepad module, potentially exposing sensitive user information.
Affected Products
- Huawei HarmonyOS 5.0.1
- Huawei HarmonyOS 5.1.0
- Huawei HarmonyOS 6.0.0

Technical Details for CVE-2025-68965
Vulnerability Analysis
This vulnerability resides within the Notepad module of HarmonyOS and is classified under CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor). The flaw enables a local attacker with basic user privileges to bypass permission controls and access confidential data that should be restricted.
The attack requires local access to the device, meaning an attacker must already have some level of access to the HarmonyOS system. However, once local access is obtained, exploitation does not require user interaction, making it relatively straightforward for an attacker to leverage. The vulnerability specifically impacts confidentiality without affecting system integrity or availability.
Root Cause
The root cause of CVE-2025-68965 lies in insufficient permission validation within the Notepad module. The application fails to properly enforce access control policies when handling data requests, allowing processes or users without appropriate authorization to read sensitive information. This represents a classic case of broken access control where the permission checking mechanism does not adequately verify the requestor's authorization level before granting access to protected resources.
Attack Vector
The attack vector for this vulnerability is local, requiring the attacker to have existing access to the target HarmonyOS device. The exploitation process involves:
- The attacker gains local access to a HarmonyOS device running a vulnerable version (5.0.1, 5.1.0, or 6.0.0)
- With low-level privileges, the attacker interacts with the Notepad module
- Due to improper permission controls, the attacker can bypass access restrictions
- Confidential data stored within the Notepad application becomes accessible to the unauthorized user
The vulnerability does not require elevated privileges or user interaction to exploit, lowering the barrier for successful attacks on affected devices.
Detection Methods for CVE-2025-68965
Indicators of Compromise
- Unusual access patterns to Notepad module data files or databases by non-standard processes
- Unexpected inter-process communication requests targeting the Notepad service
- Anomalous read operations on Notepad data directories from low-privilege contexts
- System logs showing permission checks being bypassed for Notepad-related operations
Detection Strategies
- Monitor for unauthorized access attempts to Notepad module storage locations
- Implement application-level logging to track data access requests within the Notepad module
- Deploy endpoint detection solutions capable of identifying permission bypass attempts on HarmonyOS devices
- Review system audit logs for unusual process behavior targeting Notepad components
Monitoring Recommendations
- Enable enhanced logging for the Notepad module and related system services
- Configure alerts for abnormal data access patterns on HarmonyOS devices
- Regularly audit user permissions and access control configurations
- Deploy SentinelOne agents on compatible endpoints to provide real-time threat detection and response capabilities
How to Mitigate CVE-2025-68965
Immediate Actions Required
- Update affected HarmonyOS devices to the latest patched version available from Huawei
- Review and restrict user access permissions on shared or enterprise-managed devices
- Monitor affected devices for signs of exploitation until patches can be applied
- Limit physical access to devices running vulnerable HarmonyOS versions
Patch Information
Huawei has released security updates addressing this vulnerability in their January 2026 security bulletins. Organizations and users should apply the latest HarmonyOS updates as soon as possible. For detailed patch information, refer to the following official Huawei security advisories:
- Huawei Security Bulletin 2026-1
- Huawei Laptop Security Bulletin 2026-1
- Huawei Vision Security Bulletin 2026-1
Workarounds
- Restrict the use of the Notepad application for storing sensitive information until patches are applied
- Implement additional access controls at the device management level to limit exposure
- Consider disabling or restricting the Notepad module on enterprise-managed devices if not essential for business operations
- Ensure devices are not left unattended or accessible to unauthorized users
