Ubuntu 4710-1: Linux kernel vulnerability
Summary
Update Instructions
The problem can be corrected by updating your system to the following package versions: Ubuntu 18.04 LTS: linux-image-4.15.0-135-generic 4.15.0-135.139 linux-image-4.15.0-135-generic-lpae 4.15.0-135.139 linux-image-4.15.0-135-lowlatency 4.15.0-135.139 linux-image-generic 4.15.0.135.122 linux-image-generic-lpae 4.15.0.135.122 linux-image-lowlatency 4.15.0.135.122 linux-image-powerpc-e500mc 4.15.0.135.122 linux-image-powerpc-smp 4.15.0.135.122 linux-image-powerpc64-emb 4.15.0.135.122 linux-image-powerpc64-smp 4.15.0.135.122 linux-image-virtual 4.15.0.135.122 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.
