How to pull a report of server name/id and kernel version of all servers in AWS?

Question

• I am using SSM to run uname -srm to identify the kernel versions of all the EC2 instances in a bunch of AWS accounts in my project.

• And I'm storing the results of SSM commands on S3

• Next I'm downloading the S3 contents and doing a grep on the results to see if there's a kernel 5.x being used

Is there a better way to automate this search? I just need a report of instance name/id, kernel vsersion.

I am doing this search to identify which servers are affected by the Dirty Pipe Linux kernel vuln (CVE-2022-0847).
