Ubuntu 3678-1: Linux kernel vulnerabilities
Summary
Update Instructions
The problem can be corrected by updating your system to the following package versions: Ubuntu 18.04 LTS: linux-image-4.15.0-1009-gcp 4.15.0-1009.9 linux-image-4.15.0-1010-aws 4.15.0-1010.10 linux-image-4.15.0-1011-kvm 4.15.0-1011.11 linux-image-4.15.0-23-generic 4.15.0-23.25 linux-image-4.15.0-23-generic-lpae 4.15.0-23.25 linux-image-4.15.0-23-lowlatency 4.15.0-23.25 linux-image-4.15.0-23-snapdragon 4.15.0-23.25 linux-image-aws 4.15.0.1010.10 linux-image-gcp 4.15.0.1009.11 linux-image-generic 4.15.0.23.25 linux-image-generic-lpae 4.15.0.23.25 linux-image-gke 4.15.0.1009.11 linux-image-kvm 4.15.0.1011.11 linux-image-lowlatency 4.15.0.23.25 linux-image-snapdragon 4.15.0.23.25 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.
