CVE-2025-58294 is a permissions and access control vulnerability classified under CWE-264, found in the print module of Huawei's HarmonyOS, specifically versions 5.0.1, 5.1.0, and 6.0.0. The vulnerability arises from improper enforcement of permission checks within the print service, allowing an attacker without any privileges or user interaction to access confidential service data. The CVSS 3.1 vector (AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N) indicates that the attack requires local access but no privileges or user interaction, and it impacts confidentiality with high impact, while integrity and availability remain unaffected. The flaw could allow unauthorized disclosure of sensitive information handled by the print service, potentially exposing confidential documents or system data. No patches are currently linked, and no known exploits have been reported in the wild, suggesting this is a newly disclosed vulnerability. The print module is a critical component for document handling, and unauthorized access here could undermine trust in device security. The vulnerability's local attack vector means that attackers must have some form of local access, such as physical access or local network access with device control, to exploit it. This limits the attack surface but still poses a risk in environments where devices are shared or insufficiently secured. The vulnerability was reserved in August 2025 and published in late November 2025, indicating recent discovery and disclosure.

For European organizations, this vulnerability could lead to unauthorized disclosure of confidential information processed by Huawei devices running affected HarmonyOS versions, particularly in environments where printing services handle sensitive documents. Sectors such as government, finance, healthcare, and critical infrastructure that rely on secure document handling may face increased risk. The local access requirement reduces the likelihood of remote exploitation but raises concerns in shared or physically accessible environments, such as offices or public spaces. Confidentiality breaches could result in data leaks, regulatory non-compliance (e.g., GDPR), and reputational damage. Since integrity and availability are not impacted, operational disruption is unlikely, but data confidentiality compromise alone is significant. The lack of known exploits provides a window for mitigation before active attacks emerge. However, the medium severity score suggests organizations should not underestimate the risk, especially where Huawei devices are prevalent.

1. Monitor Huawei's official channels for patches addressing CVE-2025-58294 and apply them promptly once available. 2. Restrict physical and local network access to devices running affected HarmonyOS versions to trusted personnel only. 3. Implement strict access controls and user authentication mechanisms around printing services to prevent unauthorized local access. 4. Audit and monitor print service logs for unusual access patterns or attempts to access confidential data. 5. Where possible, isolate printing devices on segmented networks to limit local attack vectors. 6. Educate users about the risks of local device access and enforce policies to prevent unauthorized use. 7. Consider deploying endpoint detection and response (EDR) solutions capable of detecting anomalous local activities related to printing services. 8. Evaluate alternative secure printing solutions if patching is delayed or devices cannot be updated promptly. 9. Review and harden device configurations to minimize exposed services and unnecessary permissions. 10. Coordinate with Huawei support for guidance and potential workarounds until patches are released.
