Ubuntu 20.04 LTS USN-5809-1 Critical: Linux Kernel Buffer Overflow

The problem can be corrected by updating your system to the following package versions: Ubuntu 20.04 LTS: linux-image-5.14.0-1056-oem 5.14.0-1056.63 linux-image-oem-20.04 5.14.0.1056.54 linux-image-oem-20.04b 5.14.0.1056.54 linux-image-oem-20.04c 5.14.0.1056.54 linux-image-oem-20.04d 5.14.0.1056.54 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.
