Ubuntu Security Notice USN-7810-3
October 14, 2025

linux-azure-fips vulnerabilities
==========================================================================

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

- Ubuntu 22.04 LTS

Summary:

Several security issues were fixed in the Linux kernel.

Software Description:
- linux-azure-fips: Linux kernel for Microsoft Azure Cloud systems with FIPS

Details:

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:
  - Network drivers;
  - Packet sockets;
  - Network traffic control;
  - VMware vSockets driver;
(CVE-2025-38477, CVE-2025-38617, CVE-2025-38618, CVE-2025-38683)

Update instructions:

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

Ubuntu 22.04 LTS
  linux-image-5.15.0-1097-azure-fips  5.15.0-1097.106+fips1
                                  Available with Ubuntu Pro
  linux-image-azure-fips          5.15.0.1097.82
                                  Available with Ubuntu Pro
  linux-image-azure-fips-5.15     5.15.0.1097.82
                                  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.
