Background
The Linux kernel is the core component of the Linux operating system, responsible for managing system resources and facilitating communication between hardware and software. It is widely used across various platforms, including servers, desktops, and embedded systems. The kernel's extensive functionality and adaptability make it a critical component, but it also exposes it to potential vulnerabilities, such as the out-of-bounds read issue identified in CVE-2022-0400.
