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:
   - GPU drivers;
   - Network drivers;
   - SCSI drivers;
   - F2FS file system;
   - BPF subsystem;
   - IPv4 networking;
 (CVE-2024-42160, CVE-2024-42159, CVE-2024-42154, CVE-2024-41009,
 CVE-2024-42228, CVE-2024-42224)

Update instructions:

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

Ubuntu 24.04 LTS
  linux-image-6.8.0-1015-azure    6.8.0-1015.17
  linux-image-6.8.0-1015-azure-fde  6.8.0-1015.17
  linux-image-azure               6.8.0-1015.17
  linux-image-azure-fde           6.8.0-1015.17

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.
