Ubuntu 3676-1: 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-4.4.0-1027-kvm 4.4.0-1027.32 linux-image-4.4.0-1061-aws 4.4.0-1061.70 linux-image-4.4.0-1091-raspi2 4.4.0-1091.99 linux-image-4.4.0-1094-snapdragon 4.4.0-1094.99 linux-image-4.4.0-128-generic 4.4.0-128.154 linux-image-4.4.0-128-generic-lpae 4.4.0-128.154 linux-image-4.4.0-128-lowlatency 4.4.0-128.154 linux-image-4.4.0-128-powerpc-e500mc 4.4.0-128.154 linux-image-4.4.0-128-powerpc-smp 4.4.0-128.154 linux-image-4.4.0-128-powerpc64-emb 4.4.0-128.154 linux-image-4.4.0-128-powerpc64-smp 4.4.0-128.154 linux-image-aws 4.4.0.1061.63 linux-image-generic 4.4.0.128.134 linux-image-generic-lpae 4.4.0.128.134 linux-image-kvm 4.4.0.1027.26 linux-image-lowlatency 4.4.0.128.134 linux-image-powerpc-e500mc 4.4.0.128.134 linux-image-powerpc-smp 4.4.0.128.134 linux-image-powerpc64-emb 4.4.0.128.134 linux-image-powerpc64-smp 4.4.0.128.134 linux-image-raspi2 4.4.0.1091.91 linux-image-snapdragon 4.4.0.1094.86 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.
