- linux-gcp: Linux kernel for Google Cloud Platform (GCP) systems
- linux-lowlatency: Linux low latency kernel
- linux-nvidia: Linux kernel for NVIDIA systems
- linux-xilinx-zynqmp: Linux kernel for Xilinx ZynqMP processors
- linux-lowlatency-hwe-5.15: Linux low latency kernel

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 subsystem:
   - Netfilter;
(CVE-2024-26924, CVE-2024-26643)

Ubuntu 20.04 LTS
   linux-image-5.15.0-113-lowlatency  5.15.0-113.123~20.04.1
   linux-image-5.15.0-113-lowlatency-64k  5.15.0-113.123~20.04.1
   linux-image-lowlatency-64k-hwe-20.04  5.15.0.113.123~20.04.1

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.
