(CVE-2024-50051, CVE-2025-37752, CVE-2024-53130, CVE-2024-47685,
CVE-2024-27074, CVE-2023-52477, CVE-2024-50202, CVE-2021-47345,
CVE-2024-57996, CVE-2024-53131)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 16.04 LTS
linux-image-4.4.0-1117-fips 4.4.0-1117.124
Available with Ubuntu Pro
linux-image-fips 4.4.0.1117.118
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.
