Ubuntu 4007-2: Linux kernel (HWE) vulnerability
Summary
Update Instructions
The problem can be corrected by updating your system to the following package versions: Ubuntu 16.04 LTS: linux-image-4.15.0-1014-oracle 4.15.0-1014.16~16.04.1 linux-image-4.15.0-1040-aws 4.15.0-1040.42~16.04.1 linux-image-4.15.0-51-generic 4.15.0-51.55~16.04.1 linux-image-4.15.0-51-generic-lpae 4.15.0-51.55~16.04.1 linux-image-4.15.0-51-lowlatency 4.15.0-51.55~16.04.1 linux-image-aws-hwe 4.15.0.1040.40 linux-image-generic-hwe-16.04 4.15.0.51.72 linux-image-generic-lpae-hwe-16.04 4.15.0.51.72 linux-image-lowlatency-hwe-16.04 4.15.0.51.72 linux-image-oem 4.15.0.51.72 linux-image-oracle 4.15.0.1014.8 linux-image-virtual-hwe-16.04 4.15.0.51.72 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.
