CVE-2025-59193 is a race condition vulnerability classified under CWE-362, affecting Windows Management Services in Microsoft Windows 11 Version 25H2 (build 10.0.26200.0). The flaw arises from improper synchronization when multiple threads or processes concurrently access shared resources, leading to inconsistent or unexpected behavior. An attacker with local, low-level privileges can exploit this condition to elevate their privileges, gaining higher access rights than intended. The vulnerability impacts confidentiality, integrity, and availability, as elevated privileges can allow unauthorized access to sensitive data, modification of system configurations, or disruption of services. The CVSS v3.1 score is 7.0, reflecting a high severity with attack vector local, attack complexity high, privileges required low, and no user interaction needed. The scope is unchanged, meaning the vulnerability affects the same security scope. Currently, there are no known exploits in the wild, and no official patches have been released, though the vulnerability was published on October 14, 2025. This vulnerability is particularly concerning because race conditions can be difficult to detect and reproduce, making mitigation and detection challenging. Organizations running Windows 11 25H2 should prioritize monitoring and prepare for patch deployment once available.

For European organizations, this vulnerability poses a significant risk due to the widespread adoption of Windows 11 in enterprise environments. Successful exploitation could allow attackers to escalate privileges locally, potentially leading to unauthorized access to sensitive information, disruption of critical services, or lateral movement within networks. This is especially critical for sectors such as finance, healthcare, government, and critical infrastructure, where confidentiality and integrity are paramount. The high impact on availability could also result in denial-of-service conditions if attackers manipulate system services. Since the attack requires local access, insider threats or attackers who have already compromised lower-privileged accounts are the primary risk vectors. The absence of known exploits currently provides a window for proactive defense, but the high severity score indicates that exploitation could have serious consequences.

1. Implement strict access controls and limit local user privileges to the minimum necessary to reduce the risk of privilege escalation. 2. Monitor system logs and Windows Management Services activity for unusual or concurrent access patterns that may indicate exploitation attempts. 3. Employ endpoint detection and response (EDR) solutions capable of detecting race condition exploitation behaviors. 4. Prepare for rapid deployment of official patches from Microsoft once released; subscribe to Microsoft security advisories for updates. 5. Conduct internal audits and penetration testing focusing on privilege escalation vectors to identify potential exploitation paths. 6. Use application whitelisting and restrict execution of unauthorized code to limit attacker capabilities post-exploitation. 7. Educate IT staff about the risks of race conditions and the importance of timely patching and monitoring.
