Ubuntu 5162-1: Linux kernel vulnerabilities
Summary
Update Instructions
The problem can be corrected by updating your system to the following package versions: Ubuntu 21.10: linux-image-5.13.0-1006-kvm 5.13.0-1006.6 linux-image-5.13.0-1007-aws 5.13.0-1007.8 linux-image-5.13.0-1007-gcp 5.13.0-1007.8 linux-image-5.13.0-1008-azure 5.13.0-1008.9 linux-image-5.13.0-1010-oracle 5.13.0-1010.12 linux-image-5.13.0-1011-raspi 5.13.0-1011.13 linux-image-5.13.0-1011-raspi-nolpae 5.13.0-1011.13 linux-image-5.13.0-22-generic 5.13.0-22.22 linux-image-5.13.0-22-generic-64k 5.13.0-22.22 linux-image-5.13.0-22-generic-lpae 5.13.0-22.22 linux-image-5.13.0-22-lowlatency 5.13.0-22.22 linux-image-aws 5.13.0.1007.9 linux-image-azure 5.13.0.1008.9 linux-image-gcp 5.13.0.1007.8 linux-image-generic 5.13.0.22.33 linux-image-generic-64k 5.13.0.22.33 linux-image-generic-lpae 5.13.0.22.33 linux-image-gke 5.13.0.1007.8 linux-image-kvm 5.13.0.1006.6 linux-image-lowlatency 5.13.0.22.33 linux-image-oem-20.04 5.13.0.22.33 linux-image-oracle 5.13.0.1010.12 linux-image-raspi 5.13.0.1011.17 linux-image-raspi-nolpae 5.13.0.1011.17 linux-image-virtual 5.13.0.22.33 Ubuntu 20.04 LTS: linux-image-5.13.0-1020-oem 5.13.0-1020.24 linux-image-oem-20.04c 5.13.0.1020.24 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.
