Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems: Nios II architecture; Sun Sparc architecture; User-Mode Linux (UML); x86 architecture; Block layer subsystem; Cryptographic API; Drivers core; Bus devices; Hardware random number generator core; Data acquisition framework and drivers; CPU frequency scaling framework; DMA engine subsystem; GPU drivers; HW tracing; Input Device (Miscellaneous) drivers; Multiple devices driver; Media drivers; MOST (Media Oriented Systems Transport) drivers; MTD block device drivers; Network drivers; NVME drivers; PCI subsystem; Performance monitor drivers; Pin controllers subsystem; x86...

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.
The problem can be corrected by updating your system to the following package versions:
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.
