Ubuntu 4711-1: Linux kernel vulnerabilities
Summary
Update Instructions
The problem can be corrected by updating your system to the following package versions: Ubuntu 18.04 LTS: linux-image-4.15.0-1064-oracle 4.15.0-1064.71 linux-image-4.15.0-1078-raspi2 4.15.0-1078.83 linux-image-4.15.0-1084-kvm 4.15.0-1084.86 linux-image-4.15.0-1093-aws 4.15.0-1093.99 linux-image-4.15.0-1095-snapdragon 4.15.0-1095.104 linux-image-aws-lts-18.04 4.15.0.1093.96 linux-image-kvm 4.15.0.1084.80 linux-image-oracle-lts-18.04 4.15.0.1064.74 linux-image-raspi2 4.15.0.1078.75 linux-image-snapdragon 4.15.0.1095.98 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.
