Ubuntu 4008-1: Linux kernel vulnerabilities
Summary
Update Instructions
The problem can be corrected by updating your system to the following package versions: Ubuntu 16.04 LTS: linux-image-4.4.0-1047-kvm 4.4.0-1047.53 linux-image-4.4.0-1084-aws 4.4.0-1084.94 linux-image-4.4.0-1110-raspi2 4.4.0-1110.118 linux-image-4.4.0-1114-snapdragon 4.4.0-1114.119 linux-image-4.4.0-150-generic 4.4.0-150.176 linux-image-4.4.0-150-generic-lpae 4.4.0-150.176 linux-image-4.4.0-150-lowlatency 4.4.0-150.176 linux-image-4.4.0-150-powerpc-e500mc 4.4.0-150.176 linux-image-4.4.0-150-powerpc-smp 4.4.0-150.176 linux-image-4.4.0-150-powerpc64-emb 4.4.0-150.176 linux-image-4.4.0-150-powerpc64-smp 4.4.0-150.176 linux-image-aws 4.4.0.1084.87 linux-image-generic 4.4.0.150.158 linux-image-generic-lpae 4.4.0.150.158 linux-image-kvm 4.4.0.1047.47 linux-image-lowlatency 4.4.0.150.158 linux-image-powerpc-e500mc 4.4.0.150.158 linux-image-powerpc-smp 4.4.0.150.158 linux-image-powerpc64-emb 4.4.0.150.158 linux-image-powerpc64-smp 4.4.0.150.158 linux-image-raspi2 4.4.0.1110.110 linux-image-snapdragon 4.4.0.1114.106 linux-image-virtual 4.4.0.150.158 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.
