Ubuntu 4678-1: Linux kernel vulnerabilities
Summary
Update Instructions
The problem can be corrected by updating your system to the following package versions: Ubuntu 20.10: linux-image-5.8.0-1011-raspi 5.8.0-1011.14 linux-image-5.8.0-1011-raspi-nolpae 5.8.0-1011.14 linux-image-5.8.0-1014-kvm 5.8.0-1014.15 linux-image-5.8.0-1014-oracle 5.8.0-1014.14 linux-image-5.8.0-1015-gcp 5.8.0-1015.15 linux-image-5.8.0-1016-azure 5.8.0-1016.17 linux-image-5.8.0-1017-aws 5.8.0-1017.18 linux-image-5.8.0-34-generic 5.8.0-34.37 linux-image-5.8.0-34-generic-64k 5.8.0-34.37 linux-image-5.8.0-34-generic-lpae 5.8.0-34.37 linux-image-5.8.0-34-lowlatency 5.8.0-34.37 linux-image-aws 5.8.0.1017.19 linux-image-azure 5.8.0.1016.16 linux-image-gcp 5.8.0.1015.15 linux-image-generic 5.8.0.34.39 linux-image-generic-64k 5.8.0.34.39 linux-image-generic-lpae 5.8.0.34.39 linux-image-gke 5.8.0.1015.15 linux-image-kvm 5.8.0.1014.16 linux-image-lowlatency 5.8.0.34.39 linux-image-oracle 5.8.0.1014.14 linux-image-raspi 5.8.0.1011.14 linux-image-raspi-nolpae 5.8.0.1011.14 linux-image-virtual 5.8.0.34.39 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.
