Ubuntu 4462-1: 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-5.0.0-1046-gke 5.0.0-1046.47 linux-image-5.0.0-1067-oem-osp1 5.0.0-1067.72 linux-image-gke-5.0 5.0.0.1046.31 linux-image-oem-osp1 5.0.0.1067.65 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.
