Ubuntu 5295-2: 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-5.13.0-1013-kvm 5.13.0-1013.14 linux-image-5.13.0-1015-gcp 5.13.0-1015.18 linux-image-5.13.0-1017-raspi 5.13.0-1017.19 linux-image-5.13.0-1017-raspi-nolpae 5.13.0-1017.19 linux-image-5.13.0-1018-oracle 5.13.0-1018.22 linux-image-5.13.0-30-generic 5.13.0-30.33 linux-image-5.13.0-30-generic-64k 5.13.0-30.33 linux-image-5.13.0-30-generic-lpae 5.13.0-30.33 linux-image-5.13.0-30-lowlatency 5.13.0-30.33 linux-image-aws 5.13.0.1014.15 linux-image-gcp 5.13.0.1015.14 linux-image-generic 5.13.0.30.40 linux-image-generic-64k 5.13.0.30.40 linux-image-generic-lpae 5.13.0.30.40 linux-image-gke 5.13.0.1015.14 linux-image-kvm 5.13.0.1013.13 linux-image-lowlatency 5.13.0.30.40 linux-image-oem-20.04 5.13.0.30.40 linux-image-oracle 5.13.0.1018.18 linux-image-raspi 5.13.0.1017.22 linux-image-raspi-nolpae 5.13.0.1017.22 linux-image-virtual 5.13.0.30.40 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.
