CVE-2025-58289 identifies a vulnerability in Huawei's HarmonyOS, specifically within the print module, where improper exception handling leads to business logic errors categorized under CWE-840. This flaw can cause the system to behave unexpectedly during print operations, potentially leading to availability issues such as denial of service. The vulnerability affects HarmonyOS versions 5.0.1 and 5.1.0. The CVSS 3.1 base score is 5.9 (medium), reflecting a local attack vector (AV:L), low attack complexity (AC:L), no privileges required (PR:N), and no user interaction (UI:N). The scope is unchanged (S:U), with low impact on confidentiality, integrity, and availability (C:L/I:L/A:L). Exploitation requires local access to the device, which limits remote exploitation possibilities. No patches are currently linked, and no known exploits have been reported in the wild. The vulnerability arises from business logic errors in exception handling, which can cause the print service to fail or crash, impacting system availability. This could disrupt normal operations on devices running the affected HarmonyOS versions, especially in environments relying heavily on printing services or automated workflows involving print functions.

For European organizations, the primary impact is potential disruption of availability on devices running affected HarmonyOS versions, which could affect business continuity if printing or related services are critical. While the confidentiality and integrity impacts are low, denial of service conditions could interrupt workflows, especially in sectors using Huawei devices extensively, such as telecommunications, manufacturing, and public services. The requirement for local access reduces the risk of widespread remote exploitation but raises concerns for insider threats or compromised local networks. Organizations with integrated Huawei HarmonyOS devices in their infrastructure may experience operational delays or require device restarts to recover from crashes. The absence of known exploits reduces immediate risk but does not eliminate the possibility of future attacks. The medium severity rating suggests moderate urgency in addressing the vulnerability to prevent potential service interruptions.

1. Monitor Huawei’s official channels for patches addressing CVE-2025-58289 and apply them promptly once available. 2. Restrict local access to devices running affected HarmonyOS versions to trusted personnel only, minimizing the risk of local exploitation. 3. Implement strict access controls and network segmentation to limit exposure of devices with printing capabilities. 4. Regularly audit and monitor print service logs and system event logs for anomalies or crashes indicative of exploitation attempts. 5. Educate users and administrators about the risks of local exploitation and encourage reporting of unusual device behavior. 6. Where feasible, consider deploying alternative printing solutions or temporarily disabling print services on critical devices until patches are applied. 7. Maintain up-to-date backups and recovery procedures to mitigate potential availability impacts. 8. Collaborate with Huawei support for guidance and early access to fixes or workarounds.
