Critical security fixes address several issues in Ubuntu's linux-azure-fips kernel, ensuring system integrity and security.
Several security issues were fixed in the Linux kernel.

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:

Josh Eads, Kristoffer Janke, Eduardo Vela Nava, Tavis Ormandy, and Matteo

Rizzo discovered that some AMD Zen processors did not properly verify the

signature of CPU microcode. This flaw is known as EntrySign. A privileged

attacker could possibly use this issue to cause load malicious CPU

microcode causing loss of integrity and confidentiality. (CVE-2024-36347)

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:

- MIPS architecture;

- PowerPC architecture;

- x86 architecture;

- Block layer subsystem;

- Cryptographic API;

- ACPI drivers;

- Network block device driver;

- Bluetooth drivers;

- Character device driver;

- TPM device driver;

- Clock framework and drivers;

- D...

Update Instructions

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

Ubuntu 24.04 LTS
  linux-image-6.8.0-1054-azure-fips  6.8.0-1054.60+fips1
                                  Available with Ubuntu Pro
  linux-image-azure-fips          6.8.0-1054.60+fips1
                                  Available with Ubuntu Pro
  linux-image-azure-fips-6.8      6.8.0-1054.60+fips1
                                  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.
