Ubuntu 4484-1: 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-5.3.0-1032-raspi2 5.3.0-1032.34 linux-image-5.3.0-1034-aws 5.3.0-1034.36 linux-image-5.3.0-1034-gke 5.3.0-1034.36 linux-image-5.3.0-66-generic 5.3.0-66.60 linux-image-5.3.0-66-lowlatency 5.3.0-66.60 linux-image-aws 5.3.0.1034.33 linux-image-gke-5.3 5.3.0.1034.19 linux-image-gkeop-5.3 5.3.0.66.123 linux-image-raspi2-hwe-18.04 5.3.0.1032.22 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.
