CVE-2025-58295: CWE-121 Stack-based Buffer Overflow in Huawei HarmonyOS
CVE-2025-58295 is a medium-severity stack-based buffer overflow vulnerability in Huawei HarmonyOS versions 5. 0. 1 and 5. 1. 0, specifically within the development framework module. Exploitation requires local access and no user interaction or privileges, potentially impacting system availability and partially compromising confidentiality and integrity. No public exploits are currently known. The vulnerability could lead to denial of service or limited code execution, affecting devices running the affected HarmonyOS versions. European organizations using Huawei devices with HarmonyOS, especially in telecommunications and IoT sectors, should prioritize patching once available and implement strict access controls. Countries with significant Huawei device deployment and strategic telecom infrastructure, such as Germany, France, and the UK, are most likely to be impacted.
AI Analysis
Technical Summary
CVE-2025-58295 is a stack-based buffer overflow vulnerability identified in Huawei's HarmonyOS development framework module, affecting versions 5.0.1 and 5.1.0. This vulnerability arises from improper bounds checking in the handling of data within the framework, allowing an attacker with local access to overwrite stack memory. The flaw is classified under CWE-121, indicating a classic stack-based buffer overflow scenario. Exploitation does not require privileges or user interaction, but the attacker must have local access to the device, such as through a compromised account or physical access. Successful exploitation can lead to partial compromise of confidentiality and integrity, but primarily affects availability by causing crashes or denial of service conditions. The CVSS v3.1 base score is 5.9 (medium), reflecting the local attack vector and moderate impact. No public exploits have been reported yet, but the vulnerability poses a risk to devices running the affected HarmonyOS versions, particularly in environments where local access controls are weak. The lack of available patches at the time of publication necessitates proactive mitigation strategies. Given Huawei's significant presence in telecommunications and IoT devices, this vulnerability could have broader implications if exploited in critical infrastructure or enterprise environments.
Potential Impact
For European organizations, the primary impact of CVE-2025-58295 is potential disruption of services due to denial of service conditions on devices running affected HarmonyOS versions. This is particularly concerning for telecom operators, IoT deployments, and enterprises relying on Huawei hardware and software. Confidentiality and integrity impacts are limited but possible, which could lead to data exposure or unauthorized modifications in worst-case scenarios. The requirement for local access reduces the risk of remote exploitation but increases the importance of internal security controls. Disruptions could affect network availability, customer services, and operational technology systems, potentially causing financial and reputational damage. The vulnerability's medium severity suggests it is not an immediate critical threat but should be addressed promptly to avoid escalation or chaining with other vulnerabilities. European organizations with Huawei device deployments must assess their exposure and implement compensating controls until patches are available.
Mitigation Recommendations
1. Restrict local access to devices running affected HarmonyOS versions by enforcing strong authentication and physical security measures. 2. Monitor system logs and behavior for signs of anomalous activity or crashes that may indicate exploitation attempts. 3. Implement network segmentation to limit lateral movement if a device is compromised. 4. Disable or limit unnecessary services and interfaces on affected devices to reduce attack surface. 5. Maintain up-to-date inventories of Huawei devices and their OS versions to identify vulnerable assets. 6. Engage with Huawei for timely patch releases and apply updates as soon as they become available. 7. Conduct regular security audits and penetration tests focusing on local access controls and device hardening. 8. Educate staff on the risks of local device compromise and enforce strict endpoint security policies. These steps go beyond generic advice by focusing on access control, monitoring, and asset management specific to the affected environment.
