CVE-2025-58293 is a vulnerability identified in Huawei's HarmonyOS, specifically affecting versions 5.1.0 and 5.0.1. The root cause is improper exception handling within the print module, categorized under CWE-264, which relates to permissions, privileges, and access control weaknesses. This flaw allows an attacker with local access and the ability to interact with the system to trigger exceptions in the print module that are not properly managed, leading to a denial of service condition. The CVSS 3.1 base score is 5.5 (medium severity), with vector AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H, indicating local attack vector, low attack complexity, no privileges required, user interaction needed, unchanged scope, no confidentiality or integrity impact, but high impact on availability. No known exploits are currently reported in the wild. The vulnerability primarily threatens system availability by causing crashes or hangs in the print service, potentially disrupting printing operations and related workflows. Since the print module is a core component for document handling, its failure can affect business continuity, especially in environments relying on HarmonyOS devices for document processing. The lack of patches at the time of reporting necessitates proactive risk management. Organizations should monitor Huawei's advisories for updates and consider temporary controls to limit exposure.

For European organizations, the primary impact is on availability, potentially causing denial of service in printing services on HarmonyOS devices. This can disrupt business operations, especially in sectors with heavy reliance on printing such as legal, finance, healthcare, and government. The vulnerability does not compromise data confidentiality or integrity, reducing risks of data breaches. However, operational interruptions can lead to productivity losses and increased support costs. Given the local access and user interaction requirements, the threat is more relevant to insider risks or scenarios where attackers have physical or remote local access. Organizations using HarmonyOS in mixed-device environments may face challenges in maintaining seamless workflows. The absence of known exploits reduces immediate risk but does not eliminate the potential for future attacks. European entities with Huawei device deployments should assess their exposure, particularly in environments where print services are critical.

1. Monitor Huawei's official channels for patches addressing CVE-2025-58293 and apply them promptly upon release. 2. Restrict local user access to HarmonyOS devices, especially limiting untrusted users from interacting with the print module. 3. Implement strict access controls and user authentication on devices to reduce the risk of unauthorized local exploitation. 4. Disable or limit printing services on devices where printing is non-essential to reduce the attack surface. 5. Employ monitoring and alerting for print service crashes or abnormal behavior to detect exploitation attempts early. 6. Educate users about the risk of interacting with suspicious print jobs or prompts that could trigger the vulnerability. 7. In environments with critical printing needs, consider fallback or redundant printing solutions to maintain availability during mitigation. 8. Conduct regular security audits of device configurations and user privileges to ensure compliance with least privilege principles.
