Ubuntu 16.04 ESM USN-5863-1 Critical: Azure Kernel Threats

The problem can be corrected by updating your system to the following package versions: Ubuntu 16.04 ESM: linux-image-4.15.0-1159-azure 4.15.0-1159.174~16.04.1 linux-image-azure 4.15.0.1159.144 After a standard system update you need to reboot your computer to make all the necessary changes. ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.
