Detail
A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 19.04 - Ubuntu 18.04 LTS - Ubuntu 16.04 LTS Summary: The system could be made to expose sensitive information. Software Description: - linux-aws: Linux kernel for Amazon Web Services (AWS) systems - linux-aws-hwe: Linux kernel for Amazon Web Services (AWS-HWE) systems Details: Andrei Vlad Lutas and Dan Lutas discovered that some x86 processors incorrectly handle SWAPGS instructions during speculative execution. A local attacker could use this to expose sensitive information (kernel memory). Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 19.04: Ubuntu 18.04 LTS: Ubuntu 16.04 LTS: 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.
