CVE-2025-58293 is a vulnerability identified in Huawei's HarmonyOS, specifically affecting versions 5.0.1 and 5.1.0. The root cause is improper exception handling within the print module, categorized under CWE-264, which relates to permissions, privileges, and access controls. This flaw allows an attacker with local access and the ability to interact with the system (user interaction required) to trigger conditions that cause the print module to mishandle exceptions, leading to a denial of service (DoS) condition that impacts system availability. The CVSS 3.1 base score is 5.5 (medium severity), with the vector indicating local attack vector (AV:L), low attack complexity (AC:L), no privileges required (PR:N), user interaction required (UI:R), unchanged scope (S:U), no confidentiality or integrity impact (C:N/I:N), and high availability impact (A:H). No known exploits have been reported in the wild, and no official patches have been released at the time of publication. The vulnerability does not allow privilege escalation or data compromise but can disrupt operations by rendering printing services or related system functions unavailable. This could affect devices relying on HarmonyOS for printing tasks or related workflows, potentially impacting business continuity in environments where these devices are used.

For European organizations, the primary impact of CVE-2025-58293 is on availability, potentially causing denial of service conditions on HarmonyOS devices during printing operations. This could disrupt business processes that depend on printing or related system functions, especially in sectors like manufacturing, logistics, or public services where HarmonyOS devices might be deployed. Although the vulnerability requires local access and user interaction, insider threats or compromised endpoints could exploit it to degrade system reliability. The lack of confidentiality or integrity impact limits data breach risks, but operational disruptions could lead to productivity losses and increased support costs. Organizations using Huawei HarmonyOS devices should be aware of this risk, particularly in environments with shared device usage or where print services are critical. The absence of known exploits reduces immediate risk, but the medium severity rating and availability impact warrant proactive mitigation.

1. Restrict local access to HarmonyOS devices, especially those running versions 5.0.1 and 5.1.0, to trusted users only. 2. Implement strict user authentication and session controls to prevent unauthorized local interactions that could trigger the vulnerability. 3. Monitor system logs and print service stability for unusual crashes or service interruptions that may indicate exploitation attempts. 4. Educate users about the risk of interacting with untrusted print jobs or applications that could exploit this vulnerability. 5. Coordinate with Huawei for timely patch deployment once official fixes are released; prioritize patching affected devices in critical environments. 6. Consider network segmentation to isolate HarmonyOS devices from broader enterprise networks to limit lateral movement in case of exploitation. 7. Employ endpoint detection and response (EDR) tools capable of detecting anomalous local activities related to print services. 8. Maintain up-to-date backups and incident response plans to quickly recover from potential denial of service impacts.
