Details:

Ziming Zhang discovered that the DRM driver for VMware Virtual GPU did not

properly handle certain error conditions, leading to a NULL pointer

dereference. A local attacker could possibly trigger this vulnerability to

cause a denial of service. (CVE-2022-38096)

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:

Update Instructions

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

Ubuntu 18.04 LTS
   linux-image-5.4.0-1142-azure    5.4.0-1142.149~18.04.1
                                   Available with Ubuntu Pro
   linux-image-azure               5.4.0.1142.149~18.04.1
                                   Available with Ubuntu Pro

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.
