CVE-2025-59220 is a race condition vulnerability classified under CWE-362 affecting the Windows Bluetooth Service component in Microsoft Windows Server 2022, specifically version 10.0.20348.0. The vulnerability arises from improper synchronization when multiple threads concurrently access shared resources, leading to a state where an attacker with authorized local access and low privileges can manipulate the timing of operations to escalate their privileges. The flaw does not require user interaction but has a high attack complexity, meaning exploitation demands precise conditions or advanced skills. The vulnerability impacts confidentiality, integrity, and availability, allowing attackers to potentially execute arbitrary code with elevated privileges or disrupt system operations. Although no public exploits are known at this time, the vulnerability's presence in a critical server OS component makes it a significant risk. The lack of available patches at the time of publication necessitates immediate attention to access controls and monitoring. This vulnerability highlights the importance of proper synchronization in concurrent programming within system services to prevent race conditions that can be leveraged for privilege escalation.

For European organizations, the impact of CVE-2025-59220 could be substantial, especially for enterprises and public sector entities relying on Windows Server 2022 for critical infrastructure and services. Successful exploitation would allow attackers to elevate privileges locally, potentially gaining administrative control over servers. This could lead to unauthorized access to sensitive data, disruption of services, and deployment of further malware or ransomware. Given the high confidentiality, integrity, and availability impact, organizations could face operational downtime, data breaches, and compliance violations under regulations such as GDPR. The requirement for local access limits remote exploitation but does not eliminate risk, as insider threats or compromised user accounts could be leveraged. The absence of known exploits currently provides a window for proactive mitigation, but the high severity score underscores the urgency of addressing this vulnerability.

1. Apply official patches from Microsoft immediately once they become available for Windows Server 2022 to address the race condition in the Bluetooth Service. 2. Until patches are released, restrict local access to Windows Server 2022 systems, especially limiting access to trusted administrators and service accounts. 3. Disable the Windows Bluetooth Service on servers where Bluetooth functionality is not required to reduce the attack surface. 4. Implement strict endpoint security controls and monitoring to detect unusual privilege escalation attempts or anomalous behavior indicative of exploitation attempts. 5. Employ application whitelisting and least privilege principles to minimize the impact of potential privilege escalations. 6. Conduct regular security audits and vulnerability assessments focusing on concurrency and synchronization issues in critical services. 7. Educate system administrators about the risks of race conditions and the importance of timely patch management.
