Other Critical Severity Vulnerabilities Patched in March Patch Tuesday Edition

CVE-2024-21407: Windows Hyper-V Remote Code Execution Vulnerability

An authenticated attacker on a guest VM must send specially crafted file operation requests to hardware resources to perform remote code execution on the host server. Successful exploitation of this vulnerability requires an attacker to gather information specific to the environment and take additional actions before exploitation to prepare the target environment.

CVE-2024-21408: Windows Hyper-V Denial of Service Vulnerability

Windows Hyper-V allows hardware virtualization. IT professionals and software developers use virtualization to test software on multiple operating systems. Hyper-V enables working professionals to perform these tasks smoothly. With the help of Hyper-V, one can create virtual hard drives, virtual switches, and numerous different virtual devices, all of which can be added to virtual machines.

Microsoft has not published any information about the vulnerability.
