Ubuntu 4577-1: 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-5.0.0-1049-gke 5.0.0-1049.50 linux-image-5.0.0-1069-oem-osp1 5.0.0-1069.75 linux-image-5.3.0-1035-raspi2 5.3.0-1035.37 linux-image-5.3.0-1038-gke 5.3.0-1038.40 linux-image-5.3.0-68-generic 5.3.0-68.63 linux-image-5.3.0-68-lowlatency 5.3.0-68.63 linux-image-gke-5.0 5.0.0.1049.33 linux-image-gke-5.3 5.3.0.1038.21 linux-image-gkeop-5.3 5.3.0.68.125 linux-image-oem-osp1 5.0.0.1069.67 linux-image-raspi2-hwe-18.04 5.3.0.1035.24 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.
