(CVE-2021-47599, CVE-2022-48875, CVE-2022-49072, CVE-2022-49267,
CVE-2024-49927, CVE-2024-56640, CVE-2025-21780, CVE-2025-40215)

Update instructions:

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

Ubuntu 20.04 LTS
  linux-image-5.4.0-1155-aws-fips  5.4.0-1155.165+fips1
                                  Available with Ubuntu Pro
  linux-image-aws-fips            5.4.0.1155.102
                                  Available with Ubuntu Pro
  linux-image-aws-fips-5.4        5.4.0.1155.102
                                  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.
