Ubuntu 5072-1: Linux kernel vulnerabilities
Summary
Update Instructions
The problem can be corrected by updating your system to the following package versions: Ubuntu 20.04 LTS: linux-image-5.10.0-1045-oem 5.10.0-1045.47 linux-image-5.8.0-1041-azure 5.8.0-1041.44~20.04.1 linux-image-azure 5.8.0.1041.44~20.04.13 linux-image-oem-20.04 5.10.0.1045.47 linux-image-oem-20.04b 5.10.0.1045.47 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.
