(CVE-2024-26929, CVE-2024-40982, CVE-2024-42311, CVE-2024-53141,
CVE-2024-41066, CVE-2024-38661, CVE-2024-38553, CVE-2024-43914,

CVE-2024-41020, CVE-2024-41012, CVE-2024-26595)

Update instructions:

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

Ubuntu 18.04 LTS
   linux-image-4.15.0-1185-azure   4.15.0-1185.200
                                   Available with Ubuntu Pro
   linux-image-azure-lts-18.04     4.15.0.1185.153
                                   Available with Ubuntu Pro

Ubuntu 14.04 LTS
   linux-image-4.15.0-1185-azure   4.15.0-1185.200~14.04.1
                                   Available with Ubuntu Pro
   linux-image-azure               4.15.0.1185.200~14.04.1
                                   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.
