(CVE-2024-46800, CVE-2024-43882)

Update instructions:

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

Ubuntu 24.04 LTS
linux-image-6.8.0-1018-azure 6.8.0-1018.21
linux-image-6.8.0-1018-azure-fde 6.8.0-1018.21
linux-image-azure 6.8.0-1018.21
linux-image-azure-fde 6.8.0-1018.21

Ubuntu 22.04 LTS
linux-image-6.8.0-1016-oracle 6.8.0-1016.17~22.04.1
linux-image-6.8.0-1016-oracle-64k 6.8.0-1016.17~22.04.1
linux-image-6.8.0-1018-azure 6.8.0-1018.21~22.04.1
linux-image-6.8.0-1018-azure-fde 6.8.0-1018.21~22.04.1
linux-image-6.8.0-1019-aws 6.8.0-1019.21~22.04.1
linux-image-aws 6.8.0-1019.21~22.04.1
linux-image-azure 6.8.0-1018.21~22.04.1
linux-image-azure-fde 6.8.0-1018.21~22.04.1
linux-image-oracle 6.8.0-1016.17~22.04.1
linux-image-oracle-64k 6.8.0-1016.17~22.04.1

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.
