AWS Inspector told me my instance had an issue "CVE-2023-46813 - kernel-headers, kernel-devel and 1 more". Looking at the affected packages:
Name

^- I found that my instance was running kernel 5.10 and needs to be upgraded to 5.15. I've tried many ways, but its still failing.
The recommended:
yum update kernel-headers
yum update kernel-devel
yum update kernel
^- did not update my kernel
Following the post (https://repost.aws/knowledge-center/amazon-linux-2-kernel-upgrade) to use amazon-linux-extras:

^- Even after I ran sudo amazon-linux-extras install kernel-5.15 -y, I'm still not seeing 5.15 inside my rpm after I reboot, its still 5.10.
My instance information:
$ cat /etc/os-release
NAME="Amazon Linux"
VERSION="2"
ID="amzn"
ID_LIKE="centos rhel fedora"
VERSION_ID="2"
PRETTY_NAME="Amazon Linux 2"
ANSI_COLOR="0;33"
CPE_NAME="cpe:2.3:o:amazon:amazon_linux:2"
HOME_URL="https://amazonlinux.com/"
SUPPORT_END="2025-06-30"
Am I doing something wrong, or why is 5.15 failing to install? Not sure if relevant, but I believe this instance was created via EKS.

Thank you for trying this out and showing that it is supposed to work - I did end up finding my issue which was that I needed to remove my versionlock.
