Ubuntu 3732-1: 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-4.15.0-1013-oem 4.15.0-1013.16 linux-image-4.15.0-1015-gcp 4.15.0-1015.15 linux-image-4.15.0-1017-aws 4.15.0-1017.17 linux-image-4.15.0-1017-kvm 4.15.0-1017.17 linux-image-4.15.0-1018-raspi2 4.15.0-1018.19 linux-image-4.15.0-1019-azure 4.15.0-1019.19 linux-image-4.15.0-30-generic 4.15.0-30.32 linux-image-4.15.0-30-generic-lpae 4.15.0-30.32 linux-image-4.15.0-30-lowlatency 4.15.0-30.32 linux-image-4.15.0-30-snapdragon 4.15.0-30.32 linux-image-aws 4.15.0.1017.17 linux-image-azure 4.15.0.1019.19 linux-image-azure-edge 4.15.0.1019.19 linux-image-gcp 4.15.0.1015.17 linux-image-generic 4.15.0.30.32 linux-image-generic-lpae 4.15.0.30.32 linux-image-gke 4.15.0.1015.17 linux-image-kvm 4.15.0.1017.17 linux-image-lowlatency 4.15.0.30.32 linux-image-oem 4.15.0.1013.15 linux-image-raspi2 4.15.0.1018.16 linux-image-snapdragon 4.15.0.30.32 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.
