Ubuntu 4005-1: Linux kernel vulnerabilities
Summary
Update Instructions
The problem can be corrected by updating your system to the following package versions: Ubuntu 19.04: linux-image-5.0.0-1007-aws 5.0.0-1007.7 linux-image-5.0.0-1007-gcp 5.0.0-1007.7 linux-image-5.0.0-1007-kvm 5.0.0-1007.7 linux-image-5.0.0-1009-raspi2 5.0.0-1009.9 linux-image-5.0.0-1013-snapdragon 5.0.0-1013.13 linux-image-5.0.0-16-generic 5.0.0-16.17 linux-image-5.0.0-16-generic-lpae 5.0.0-16.17 linux-image-5.0.0-16-lowlatency 5.0.0-16.17 linux-image-aws 5.0.0.1007.7 linux-image-gcp 5.0.0.1007.7 linux-image-generic 5.0.0.16.17 linux-image-generic-lpae 5.0.0.16.17 linux-image-gke 5.0.0.1007.7 linux-image-kvm 5.0.0.1007.7 linux-image-lowlatency 5.0.0.16.17 linux-image-raspi2 5.0.0.1009.6 linux-image-snapdragon 5.0.0.1013.6 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.
