Ubuntu Security Notice USN-7500-1
May 07, 2025

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

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

- Ubuntu 24.04 LTS

Summary:

Several security issues were fixed in the Linux kernel.

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

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:
  - Bluetooth drivers;
  - Microsoft Azure Network Adapter (MANA) driver;
(CVE-2025-21953, CVE-2024-56653)

Update instructions:

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

Ubuntu 24.04 LTS
  linux-image-6.8.0-1028-azure    6.8.0-1028.33
  linux-image-6.8.0-1028-azure-fde  6.8.0-1028.33
  linux-image-azure-fde-lts-24.04  6.8.0-1028.33
  linux-image-azure-lts-24.04     6.8.0-1028.33

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.
