Ubuntu 3848-1: 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-4.4.0-1039-kvm 4.4.0-1039.45 linux-image-4.4.0-1074-aws 4.4.0-1074.84 linux-image-4.4.0-1102-raspi2 4.4.0-1102.110 linux-image-4.4.0-1106-snapdragon 4.4.0-1106.111 linux-image-4.4.0-141-generic 4.4.0-141.167 linux-image-4.4.0-141-generic-lpae 4.4.0-141.167 linux-image-4.4.0-141-lowlatency 4.4.0-141.167 linux-image-4.4.0-141-powerpc-e500mc 4.4.0-141.167 linux-image-4.4.0-141-powerpc-smp 4.4.0-141.167 linux-image-4.4.0-141-powerpc64-emb 4.4.0-141.167 linux-image-4.4.0-141-powerpc64-smp 4.4.0-141.167 linux-image-aws 4.4.0.1074.76 linux-image-generic 4.4.0.141.147 linux-image-generic-lpae 4.4.0.141.147 linux-image-kvm 4.4.0.1039.38 linux-image-lowlatency 4.4.0.141.147 linux-image-powerpc-e500mc 4.4.0.141.147 linux-image-powerpc-smp 4.4.0.141.147 linux-image-powerpc64-emb 4.4.0.141.147 linux-image-powerpc64-smp 4.4.0.141.147 linux-image-raspi2 4.4.0.1102.102 linux-image-snapdragon 4.4.0.1106.98 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.
