A security issue was fixed in the Linux kernel.

Software Description:

- linux-azure-fde: Linux kernel for Microsoft Azure CVM cloud systems

- linux-intel-iotg: Linux kernel for Intel IoT platforms

- linux-kvm: Linux kernel for cloud environments

- linux-oracle: Linux kernel for Oracle Cloud systems

- linux-xilinx-zynqmp: Linux kernel for Xilinx ZynqMP processors

Details:

A security issue was discovered in the Linux kernel.

An attacker could possibly use this to compromise the system.

This update corrects flaws in the following subsystems:

- IPv6 networking;

- Netfilter;

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

Ubuntu 22.04 LTS
  linux-image-5.15.0-1078-xilinx-zynqmp  5.15.0-1078.82
  linux-image-5.15.0-1107-kvm     5.15.0-1107.112
  linux-image-5.15.0-1110-intel-iotg  5.15.0-1110.116
  linux-image-5.15.0-1112-oracle  5.15.0-1112.118
  linux-image-5.15.0-1120-azure-fde  5.15.0-1120.129
  linux-image-azure-fde-5.15      5.15.0.1120.129
  linux-image-azure-fde-lts-22.04  5.15.0.1120.129
  linux-image-intel-iotg          5.15.0.1110.109
  linux-image-intel-iotg-5.15     5.15.0.1110.109
  linux-image-kvm                 5.15.0.1107.103
  linux-image-kvm-5.15            5.15.0.1107.103
  linux-image-oracle-5.15         5.15.0.1112.108
  linux-image-oracle-lts-22.04    5.15.0.1112.108
  linux-image-xilinx-zynqmp       5.15.0.1078.81
  linux-image-xilinx-zynqmp-5.15  5.15.0.1078.81

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.
