Ubuntu Security Notice USN-8730-7
September 30, 2026

linux-fips vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 22.04 LTS

Summary:

A security issue was fixed in the Linux kernel.

Software Description:
- linux-fips: Linux kernel with FIPS

Details:

A security issue was discovered in the Linux kernel.
An attacker could possibly use this to compromise the system.
This update corrects flaws in the following subsystems:
  - IPv6 networking;
  - Netfilter;

Update instructions:

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

Ubuntu 22.04 LTS
  linux-image-5.15.0-191-fips     5.15.0-191.201+fips1
                                  Available with Ubuntu Pro
  linux-image-fips                5.15.0.191.112
                                  Available with Ubuntu Pro
  linux-image-fips-5.15           5.15.0.191.112
                                  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.
