- linux-azure-fde: Linux kernel for Microsoft Azure CVM cloud systems

- linux-azure-5.15: Linux kernel for Microsoft Azure cloud systems

- linux-azure-fde-5.15: Linux kernel for Microsoft Azure CVM cloud systems

Details:

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.

This update corrects flaws in the following subsystems:

Update Instructions

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

Ubuntu 22.04 LTS
  linux-image-5.15.0-1082-azure   5.15.0-1082.91
  linux-image-5.15.0-1082-azure-fde  5.15.0-1082.91.1
  linux-image-azure-fde-lts-22.04  5.15.0.1082.91.59
  linux-image-azure-lts-22.04     5.15.0.1082.80

Ubuntu 20.04 LTS
  linux-image-5.15.0-1082-azure   5.15.0-1082.91~20.04.1
  linux-image-5.15.0-1082-azure-fde  5.15.0-1082.91~20.04.1.1
  linux-image-azure               5.15.0.1082.91~20.04.1
  linux-image-azure-cvm           5.15.0.1082.91~20.04.1
  linux-image-azure-fde           5.15.0.1082.91~20.04.1.58

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.
