This update corrects flaws in the following subsystems: * ARM64 architecture; * M68K architecture; * User-Mode Linux (UML); * x86 architecture; * Accessibility subsystem; * Character device driver; * Clock framework and drivers; * CPU frequency scaling framework; * Hardware crypto device drivers; * Buffer Sharing and Synchronization framework; * FireWire subsystem; * GPU drivers; * HW tracing; * Macintosh device drivers; * Multiple devices driver; * Media drivers; * Network drivers; * Pin controllers subsystem; * S/390 drivers; * SCSI drivers; * SoundWire subsystem; * Greybus lights staging drivers; * TTY drivers; * Framebuffer layer; * Virtio drivers; * 9P... --- Show more ## Update instructions After a standard system update you need to reboot your computer to make all the necessary changes. [Learn more about how to get the fixes.](https://ubuntu.com/security/cves/about#security) 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. The problem can be corrected by updating your system to the following package versions: | Ubuntu Release | Package Version | | --- | --- | | 18.04 LTS bionic | [linux-image-5.4.0-1135-azure](https://launchpad.net/ubuntu/+source/linux-signed-azure-5.4) –  5.4.0-1135.142~18.04.1   Ubuntu Pro | | | | [linux-image-azure](https://launchpad.net/ubuntu/+source/linux-meta-azure-5.4) –  5.4.0.1135.142~18.04.1   Ubuntu Pro | | | --- ### Reduce your security exposure Ubuntu Pro provides ten-year security coverage to 25,000+ packages in Main and Universe repositories, and it is free for up to five machines.
