CVE-2025-58307 is a Use After Free (CWE-416) vulnerability identified in the screen recording framework module of Huawei's HarmonyOS, affecting versions 5.0.1, 5.1.0, and 6.0.0. Use After Free vulnerabilities occur when a program continues to use memory after it has been freed, leading to undefined behavior such as memory corruption, crashes, or potential code execution. In this case, the vulnerability resides in the screen recording component, which is responsible for capturing and processing screen content. Exploiting this flaw requires local access with high privileges (as indicated by CVSS vector AV:L/PR:H), and no user interaction is needed. The vulnerability impacts confidentiality, integrity, and availability, with the potential to cause system crashes or instability, thereby affecting device availability. The CVSS score of 6.4 reflects a medium severity level, primarily due to the high complexity of gaining the required privileges and the local attack vector. No public exploits have been reported yet, and no patches are currently linked, indicating that mitigation may rely on vendor updates in the near future. The vulnerability's presence in a core OS component used for screen recording means that affected devices could be disrupted, potentially impacting users relying on these features for business or personal use.

For European organizations, the impact of CVE-2025-58307 could be significant in environments where Huawei HarmonyOS devices are deployed, particularly in sectors such as telecommunications, government, and enterprises using Huawei hardware for mobile or IoT solutions. The vulnerability could lead to denial of service conditions by crashing devices or destabilizing the OS, affecting operational continuity. Confidentiality and integrity impacts are also possible if the vulnerability is leveraged to manipulate memory, although exploitation complexity and required privileges limit widespread abuse. Organizations relying on HarmonyOS for critical communications or data processing may face interruptions, potentially affecting productivity and service availability. Given the local attack vector and high privilege requirement, insider threats or compromised devices pose the greatest risk. Additionally, disruption in screen recording functionality could affect compliance or monitoring processes that depend on this feature.

1. Monitor Huawei's official security advisories and apply patches promptly once released to address this vulnerability. 2. Restrict high-privilege access on HarmonyOS devices to trusted administrators only, minimizing the risk of local exploitation. 3. Implement strict device usage policies to prevent unauthorized local access, including physical security controls. 4. Employ endpoint detection and response (EDR) solutions capable of monitoring unusual memory usage or crashes related to screen recording processes. 5. Disable or limit screen recording functionality on devices where it is not essential, reducing the attack surface. 6. Conduct regular security audits and vulnerability assessments on HarmonyOS devices within the organization. 7. Educate users and administrators about the risks of local privilege misuse and enforce strong authentication mechanisms for privileged accounts.
