Kali Linux 2018.1 is the operating system’s first snapshot for the new year, which can be used by users for new deployments or if they planned on reinstalling their Kali Linux computers because of various reasons. Being based on Debian, it goes without saying that this release includes all the latest updates and security fixes from upstream. While it comes with the Linux 4.14.12 kernel, Offensive Security promises to upgrade it to the most recent Linux 4.15 kernel release.
