Based on the long-term supported Ubuntu 16.04 LTS (Xenial Xerus) operating system, Black Lab Enterprise Linux 8 Service Pack 1 (SP1) is now powered by Linux kernel 4.4.0-45.66, the same version used upstream, which is patched against the nasty “Dirty COW” bug that could have allowed a local attacker to gain administrative privileges. Now that Canonical is offering kernel live patch services for its Ubuntu 16.04 LTS release, Black Lab Linux developers also implemented the well-known Kspice tool for offering users rebootless kernel installs. Additionally, Black Lab Enterprise Linux 8 SP1 adds full UEFI support and the ability to install Snap packages.
