Summary

A Windows Kernel-Mode Driver vulnerability enables local attackers to execute a double-free exploit that requires no user interaction and minimal privileges to achieve SYSTEM-level access. This vulnerability affects Windows operating systems and has a CVSS base score of 7.8, indicating high severity. The vulnerability is classified as a Double Free (CWE-415) issue.

Impact

The impact of this vulnerability is severe. Successful exploitation can lead to complete compromise of system confidentiality, integrity, and availability through kernel-level access. An attacker with low-level privileges can potentially escalate to SYSTEM-level permissions, effectively taking full control of the affected system. This could result in unauthorized data access, system modifications, and potential service disruptions.

Exploitation

There is no evidence that a public proof-of-concept exists. There is no evidence of proof of exploitation at the moment.

Patch

A patch for this vulnerability is available. Microsoft released the patch on November 12, 2024. Security teams should prioritize applying this patch to all affected Windows systems as soon as possible.

Mitigation

To mitigate this vulnerability, the following steps are recommended: 1. Apply the patch released by Microsoft immediately to all affected Windows systems. 2. Implement the principle of least privilege, ensuring users and processes operate with minimal necessary permissions. 3. Regularly update and patch Windows operating systems and kernel-mode drivers. 4. Monitor systems for suspicious activities, particularly attempts at privilege escalation. 5. Use endpoint detection and response (EDR) solutions to detect and prevent exploitation attempts. 6. Consider implementing application whitelisting to prevent unauthorized code execution. 7. Restrict local access to critical systems where possible.
