==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:

Summary:
Several security issues were fixed in the Linux kernel.
Software Description:
- linux-aws-5.15: Linux kernel for Amazon Web Services (AWS) systems
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 subsystems:

- Netlink;
(CVE-2024-26700, CVE-2025-38727, CVE-2023-52593, CVE-2024-26896)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 20.04 LTS
linux-image-5.15.0-1095-aws 5.15.0-1095.102~20.04.1
Available with Ubuntu Pro
linux-image-aws 5.15.0.1095.102~20.04.1
Available with Ubuntu Pro
linux-image-aws-5.15 5.15.0.1095.102~20.04.1
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.
