CVE-2021-33772

Name of the Vulnerable Software and Affected Versions Windows versions prior to the fixed version

Description The issue is related to a denial-of-service vulnerability in the implementation of the TCP/IP protocol in Microsoft Windows, caused by insufficient input validation. This can be exploited by a remote attacker to cause a denial of service by sending specially crafted input to the application.

Recommendations For Windows versions prior to the fixed version, apply the patch from the latest patchday to resolve the issue. As a temporary workaround, consider restricting access to the TCP/IP driver to minimize the risk of exploitation.
