The Linux kernel is the core component of the Linux operating system, maintaining complete control over everything in the system. It is the interface between applications and data processing at the hardware level, connecting the system hardware to the application software. The kernel manages input/output requests from software, memory, processes, peripherals and security, among other hefty responsibilities. Needless to say, the Linux kernel is pretty important. However, with power comes great responsibility, and the Linux kernel is no exception to this rule. Kernel security is critical: it determines the security of the Linux operating system as a whole, as well as the security of every individual system that runs on Linux. Vulnerabilities in the kernel can have serious implications for Linux users, and it is extremely important that users stay up-to-date on news and advisories pertaining to kernel security.
