Ubuntu Security Notice USN-7448-1
April 23, 2025

linux-azure, linux-azure-6.11 vulnerabilities
==========================================================================

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

- Ubuntu 24.10
- 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
- linux-azure-6.11: Linux kernel for Microsoft Azure cloud systems

Details:

It was discovered that the CIFS network file system implementation in the
Linux kernel did not properly verify the target namespace when handling
upcalls. An attacker could use this to expose sensitive information.
(CVE-2025-2312)

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 24.10
  linux-image-6.11.0-1013-azure   6.11.0-1013.13
  linux-image-6.11.0-1013-azure-fde  6.11.0-1013.13
  linux-image-azure               6.11.0-1013.13
  linux-image-azure-fde           6.11.0-1013.13

Ubuntu 24.04 LTS
  linux-image-6.11.0-1013-azure   6.11.0-1013.13~24.04.1
  linux-image-6.11.0-1013-azure-fde  6.11.0-1013.13~24.04.1
  linux-image-azure               6.11.0-1013.13~24.04.1
  linux-image-azure-fde           6.11.0-1013.13~24.04.1

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.
