Ubuntu Security Notice USN-7392-2
March 28, 2025

linux-azure-fips, linux-gcp-fips vulnerabilities
==========================================================================

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

- Ubuntu 20.04 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
- linux-gcp-fips: Linux kernel for Google Cloud Platform (GCP) systems with 
FIPS

Details:

Chenyuan Yang discovered that the CEC driver driver in the Linux kernel
contained a use-after-free vulnerability. A local attacker could use this
to cause a denial of service (system crash) or possibly execute arbitrary
code. (CVE-2024-23848)

Attila Szász discovered that the HFS+ file system implementation in the
Linux Kernel contained a heap overflow vulnerability. An attacker could use
a specially crafted file system image that, when mounted, could cause a
denial of service (system crash) or possibly execute arbitrary code.
(CVE-2025-0927)

Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.

Update instructions:

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

Ubuntu 20.04 LTS
   linux-image-5.4.0-1145-gcp-fips  5.4.0-1145.154+fips1
                                   Available with Ubuntu Pro
   linux-image-5.4.0-1147-azure-fips  5.4.0-1147.154+fips1
                                   Available with Ubuntu Pro
   linux-image-azure-fips          5.4.0.1147.85
                                   Available with Ubuntu Pro
   linux-image-gcp-fips            5.4.0.1145.87
                                   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.
