Ubuntu 5062-1: Linux kernel vulnerability
Summary
Update Instructions
The problem can be corrected by updating your system to the following package versions: Ubuntu 16.04 ESM: linux-image-4.4.0-1097-kvm 4.4.0-1097.106 linux-image-4.4.0-1132-aws 4.4.0-1132.146 linux-image-4.4.0-214-generic 4.4.0-214.246 linux-image-4.4.0-214-lowlatency 4.4.0-214.246 linux-image-aws 4.4.0.1132.137 linux-image-generic 4.4.0.214.221 linux-image-kvm 4.4.0.1097.95 linux-image-lowlatency 4.4.0.214.221 linux-image-virtual 4.4.0.214.221 Ubuntu 14.04 ESM: linux-image-4.4.0-1096-aws 4.4.0-1096.101 linux-image-4.4.0-214-generic 4.4.0-214.246~14.04.1 linux-image-4.4.0-214-lowlatency 4.4.0-214.246~14.04.1 linux-image-aws 4.4.0.1096.94 linux-image-generic-lts-xenial 4.4.0.214.187 linux-image-lowlatency-lts-xenial 4.4.0.214.187 linux-image-virtual-lts-xenial 4.4.0.214.187 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.
