HIGH Microsoft Corporation Vulnerability Alert

Product:

Windows TCP/IP

Summary

Concurrent execution using shared resource with improper synchronization in Windows TCP/IP allows an authorized attacker to elevate privileges locally. This vulnerability can lead to significant security risks if exploited. Attackers can take advantage of this race condition to gain unauthorized access to system resources.

Details

Severity Base Score CVE
HIGH 7 CVE-2026-27921

Exploitation

To exploit this vulnerability, an attacker must have local access to the system and be able to execute code. By manipulating the timing of operations that access shared resources, the attacker can create a race condition that allows them to elevate their privileges. This requires a high level of skill and knowledge of the system’s operation.

Affected Products

  • Windows TCP/IP: Vulnerable to privilege escalation due to improper synchronization in concurrent execution.

Mitigation

To mitigate this vulnerability, it is recommended to apply the latest security updates provided by Microsoft. Regularly updating systems and monitoring for unusual activity can help prevent exploitation. Additionally, restricting local access to sensitive systems can reduce the risk of an attacker gaining the necessary access to exploit this vulnerability.
