The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition when the Windows Hyper-V Network Switch on a host operating system fails to properly validate input from an authenticated user on a guest operating system. A remote authenticated user on a guest operating system can run a specially crafted application that could cause the Hyper-V host operating system to disclose memory information.
