Ubuntu 3819-1: Linux kernel vulnerability
Summary
Update Instructions
The problem can be corrected by updating your system to the following package versions: Ubuntu 18.10: linux-image-4.18.0-1003-gcp 4.18.0-1003.4 linux-image-4.18.0-1004-aws 4.18.0-1004.5 linux-image-4.18.0-1004-kvm 4.18.0-1004.4 linux-image-4.18.0-1006-raspi2 4.18.0-1006.8 linux-image-4.18.0-11-generic 4.18.0-11.12 linux-image-4.18.0-11-generic-lpae 4.18.0-11.12 linux-image-4.18.0-11-lowlatency 4.18.0-11.12 linux-image-4.18.0-11-snapdragon 4.18.0-11.12 linux-image-aws 4.18.0.1004.4 linux-image-gcp 4.18.0.1003.3 linux-image-generic 4.18.0.11.12 linux-image-generic-lpae 4.18.0.11.12 linux-image-gke 4.18.0.1003.3 linux-image-kvm 4.18.0.1004.4 linux-image-lowlatency 4.18.0.11.12 linux-image-raspi2 4.18.0.1006.3 linux-image-snapdragon 4.18.0.11.12 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.
