Description

A flaw was found in the Linux kernel's mshv component. A malicious guest operating system could exploit this by attempting to write to read-only memory regions or execute code in non-executable regions. This can lead to an infinite fault loop, causing the virtual CPU (vCPU) to spin indefinitely and consume host resources, resulting in a Denial of Service (DoS) for the host system.
