Ubuntu 3820-1: 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-4.15.0-1024-gcp 4.15.0-1024.25 linux-image-4.15.0-1026-kvm 4.15.0-1026.26 linux-image-4.15.0-1026-oem 4.15.0-1026.31 linux-image-4.15.0-1027-aws 4.15.0-1027.27 linux-image-4.15.0-1028-raspi2 4.15.0-1028.30 linux-image-4.15.0-1031-azure 4.15.0-1031.32 linux-image-4.15.0-39-generic 4.15.0-39.42 linux-image-4.15.0-39-generic-lpae 4.15.0-39.42 linux-image-4.15.0-39-lowlatency 4.15.0-39.42 linux-image-4.15.0-39-snapdragon 4.15.0-39.42 linux-image-aws 4.15.0.1027.27 linux-image-azure 4.15.0.1031.31 linux-image-gcp 4.15.0.1024.26 linux-image-generic 4.15.0.39.41 linux-image-generic-lpae 4.15.0.39.41 linux-image-gke 4.15.0.1024.26 linux-image-kvm 4.15.0.1026.26 linux-image-lowlatency 4.15.0.39.41 linux-image-oem 4.15.0.1026.31 linux-image-raspi2 4.15.0.1028.26 linux-image-snapdragon 4.15.0.39.41 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.
