Ubuntu 3903-1: Linux kernel vulnerabilities
Summary
Update Instructions
The problem can be corrected by updating your system to the following package versions: Ubuntu 18.10: linux-image-4.18.0-1007-gcp 4.18.0-1007.8 linux-image-4.18.0-1008-kvm 4.18.0-1008.8 linux-image-4.18.0-1010-raspi2 4.18.0-1010.12 linux-image-4.18.0-1013-azure 4.18.0-1013.13 linux-image-4.18.0-16-generic 4.18.0-16.17 linux-image-4.18.0-16-generic-lpae 4.18.0-16.17 linux-image-4.18.0-16-lowlatency 4.18.0-16.17 linux-image-4.18.0-16-snapdragon 4.18.0-16.17 linux-image-azure 4.18.0.1013.14 linux-image-gcp 4.18.0.1007.7 linux-image-generic 4.18.0.16.17 linux-image-generic-lpae 4.18.0.16.17 linux-image-gke 4.18.0.1007.7 linux-image-kvm 4.18.0.1008.8 linux-image-lowlatency 4.18.0.16.17 linux-image-raspi2 4.18.0.1010.7 linux-image-snapdragon 4.18.0.16.17 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.
