  - Network drivers;
  - SCSI drivers;

(CVE-2024-42228, CVE-2024-42154, CVE-2024-42160, CVE-2024-42159,
CVE-2024-41009, CVE-2024-42224)

Update instructions:

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

Ubuntu 22.04 LTS
  linux-image-6.8.0-1013-oracle   6.8.0-1013.13~22.04.1
  linux-image-6.8.0-1013-oracle-64k  6.8.0-1013.13~22.04.1
  linux-image-6.8.0-1016-aws      6.8.0-1016.17~22.04.2
  linux-image-aws                 6.8.0-1016.17~22.04.2
  linux-image-oracle              6.8.0-1013.13~22.04.1
  linux-image-oracle-64k          6.8.0-1013.13~22.04.1

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.
