Ubuntu 3797-1: 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-4.4.0-1036-kvm 4.4.0-1036.42 linux-image-4.4.0-1070-aws 4.4.0-1070.80 linux-image-4.4.0-1099-raspi2 4.4.0-1099.107 linux-image-4.4.0-1103-snapdragon 4.4.0-1103.108 linux-image-4.4.0-138-generic 4.4.0-138.164 linux-image-4.4.0-138-generic-lpae 4.4.0-138.164 linux-image-4.4.0-138-lowlatency 4.4.0-138.164 linux-image-4.4.0-138-powerpc-e500mc 4.4.0-138.164 linux-image-4.4.0-138-powerpc-smp 4.4.0-138.164 linux-image-4.4.0-138-powerpc64-emb 4.4.0-138.164 linux-image-4.4.0-138-powerpc64-smp 4.4.0-138.164 linux-image-aws 4.4.0.1070.72 linux-image-generic 4.4.0.138.144 linux-image-generic-lpae 4.4.0.138.144 linux-image-kvm 4.4.0.1036.35 linux-image-lowlatency 4.4.0.138.144 linux-image-powerpc-e500mc 4.4.0.138.144 linux-image-powerpc-smp 4.4.0.138.144 linux-image-powerpc64-emb 4.4.0.138.144 linux-image-powerpc64-smp 4.4.0.138.144 linux-image-raspi2 4.4.0.1099.99 linux-image-snapdragon 4.4.0.1103.95 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.
