Ubuntu 20.04 LTS: USN-5623-1 Critical Denial of Service Flaws

The problem can be corrected by updating your system to the following package versions: Ubuntu 20.04 LTS: linux-image-5.15.0-48-generic 5.15.0-48.54~20.04.1 linux-image-5.15.0-48-generic-64k 5.15.0-48.54~20.04.1 linux-image-5.15.0-48-generic-lpae 5.15.0-48.54~20.04.1 linux-image-5.15.0-48-lowlatency 5.15.0-48.54~20.04.1 linux-image-5.15.0-48-lowlatency-64k 5.15.0-48.54~20.04.1 linux-image-generic-64k-hwe-20.04 5.15.0.48.54~20.04.18 linux-image-generic-hwe-20.04 5.15.0.48.54~20.04.18 linux-image-generic-lpae-hwe-20.04 5.15.0.48.54~20.04.18 linux-image-lowlatency-64k-hwe-20.04 5.15.0.48.54~20.04.16 linux-image-lowlatency-hwe-20.04 5.15.0.48.54~20.04.16 linux-image-virtual-hwe-20.04 5.15.0.48.54~20.04.18 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.
