CVE-2026-24924 is a vulnerability classified under CWE-264, indicating improper permissions, privileges, or access controls within Huawei's HarmonyOS print module, specifically version 6.0.0. The flaw arises from insufficient enforcement of permission checks, allowing a local attacker with low privileges to access confidential service data without requiring user interaction. The CVSS 3.1 score of 6.1 reflects a medium severity, with the vector AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:L indicating local attack vector, low attack complexity, low privileges required, no user interaction, unchanged scope, high confidentiality impact, no integrity impact, and low availability impact. The vulnerability does not affect integrity or availability but compromises confidentiality by potentially exposing sensitive information handled by the print service. No known exploits have been reported in the wild, and no patches are currently available, suggesting the need for proactive mitigation. The vulnerability's local nature means attackers must already have some access to the device, but the low privilege requirement lowers the barrier for exploitation. This flaw could be exploited in environments where HarmonyOS devices are used, particularly in enterprise or governmental contexts where print services handle sensitive documents. The lack of patches necessitates immediate attention to access control policies and monitoring to prevent exploitation.

For European organizations, this vulnerability poses a confidentiality risk, especially in sectors such as government, finance, healthcare, and critical infrastructure where sensitive documents may be printed or processed on HarmonyOS devices. Unauthorized access to confidential print service data could lead to information leakage, intellectual property theft, or exposure of personal data, potentially violating GDPR and other data protection regulations. The local attack vector limits remote exploitation, but insider threats or compromised devices could be leveraged to exploit this vulnerability. The medium severity suggests a moderate risk level, but the potential impact on confidentiality could have significant reputational and regulatory consequences. Organizations relying on Huawei HarmonyOS devices for printing or document handling should consider this vulnerability in their risk assessments and incident response planning.

1. Implement strict access controls on HarmonyOS devices, ensuring that only trusted users have local access, especially to print services. 2. Monitor and audit local user activities on devices running HarmonyOS to detect unusual access patterns or privilege escalations. 3. Restrict installation and execution of untrusted applications that could exploit local privileges. 4. Isolate print services where possible, using containerization or sandboxing techniques to limit the impact of potential exploits. 5. Engage with Huawei for timely patches or updates addressing this vulnerability and plan for rapid deployment once available. 6. Educate users about the risks of local privilege misuse and enforce strong endpoint security policies. 7. Consider network segmentation to limit lateral movement from compromised devices. 8. Employ endpoint detection and response (EDR) solutions capable of identifying suspicious local activity related to print services.
