CVE-2025-59195: CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') in Microsoft Windows 11 Version 25H2
Concurrent execution using shared resource with improper synchronization ('race condition') in Microsoft Graphics Component allows an authorized attacker to deny service locally.
AI Analysis
Technical Summary
CVE-2025-59195 is a race condition vulnerability classified under CWE-362, affecting the Microsoft Graphics Component in 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 unpredictable behavior. An authorized attacker with low privileges on the local machine can exploit this condition to cause a denial of service (DoS), typically by triggering system crashes or rendering the graphics subsystem unstable. The vulnerability does not require user interaction but has a high attack complexity, meaning exploitation demands precise timing and conditions. The CVSS v3.1 score of 7.0 reflects high severity due to impacts on confidentiality, integrity, and availability, though the attack vector is local and requires privileges. No public exploits are known at this time, and no patches have been released yet. The vulnerability could be leveraged to disrupt critical services or user productivity, especially in environments where Windows 11 25H2 is widely deployed. The race condition could also potentially be a stepping stone for privilege escalation or further attacks if combined with other vulnerabilities, though this is not explicitly stated. The lack of patch availability necessitates proactive mitigation and monitoring.
Potential Impact
For European organizations, this vulnerability poses a significant risk of local denial of service, which can disrupt business operations, especially in sectors relying heavily on Windows 11 25H2 systems such as finance, healthcare, and government. The potential for system crashes or instability in the graphics subsystem could lead to loss of productivity and data integrity issues. Confidentiality could be indirectly impacted if the DoS leads to system reboots or failures during sensitive operations. Organizations with remote or hybrid workforces using Windows 11 devices may face increased exposure if attackers gain local access through compromised endpoints. Critical infrastructure and industrial control systems running Windows 11 could experience operational interruptions, affecting service availability. The high attack complexity and requirement for local privileges limit widespread exploitation but do not eliminate risk in environments with many users or shared workstations. The absence of known exploits reduces immediate threat but vigilance is necessary as exploit code could emerge.
Mitigation Recommendations
Until an official patch is released, European organizations should implement strict local access controls to limit the number of users with local privileges on Windows 11 25H2 systems. Employ application whitelisting and endpoint detection to monitor for unusual behavior targeting the graphics subsystem. Use group policies to restrict execution of untrusted code and enforce least privilege principles rigorously. Regularly audit and update antivirus and endpoint protection solutions to detect potential exploitation attempts. Implement system monitoring and logging focused on graphics component errors or crashes to detect early signs of exploitation. Educate users about the risks of local privilege misuse and enforce strong authentication for local accounts. Prepare for rapid deployment of patches once available by maintaining up-to-date asset inventories and patch management processes. Consider temporary isolation or segmentation of critical Windows 11 25H2 endpoints in sensitive environments to reduce attack surface. Engage with Microsoft security advisories for updates and guidance.
