Background
The Kernel is a crucial component of the Linux operating system that acts as a bridge between the hardware and software layers. It provides essential services and functions for the proper functioning of the system. The virtio_console module is responsible for handling communication between the virtual machine and the host system through a virtual console. This module allows the guest operating system to interact with the host system's console. However, a vulnerability has been discovered in the virtio_console module that could potentially be exploited by attackers.
Vulnerability Detail
