CVE-2024-50151, CVE-2024-50082, CVE-2024-50202)

Update instructions:

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

Ubuntu 20.04 LTS
  linux-image-5.15.0-1075-oracle  5.15.0-1075.81~20.04.1
  linux-image-5.15.0-1081-azure   5.15.0-1081.90~20.04.1
  linux-image-5.15.0-1081-azure-fde  5.15.0-1081.90~20.04.1.1
  linux-image-azure               5.15.0.1081.90~20.04.1
  linux-image-azure-cvm           5.15.0.1081.90~20.04.1
  linux-image-azure-fde           5.15.0.1081.90~20.04.1.57
  linux-image-oracle              5.15.0.1075.81~20.04.1

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.
