Name of the Vulnerable Software and Affected Versions Microsoft Hyper-V (affected versions not specified)

Description A denial of service issue exists due to insufficient input validation on the host server. This could allow a remote attacker to cause a denial of service using a specially crafted application. The attacker must have a privileged account on a guest operating system running as a virtual machine to exploit this issue. The vulnerability can be exploited by running a specially crafted application that causes the host machine to crash.

Recommendations To resolve the issue, update the system by modifying how virtual machines access the Hyper-V Network Switch. As a temporary workaround, consider restricting access to the Hyper-V Network Switch to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
