Summary

Adds a section and changelog entry for the new AWS managed policy AmazonInspector2AmiServiceRolePolicy, describing ec2, ebs, and kms permissions attached to a service-linked role used for AMI scanning.

Security assessment

The new page documents the permissions of a service-linked role policy, including reading EBS snapshot contents and using KMS decryption actions on customer managed keys. This is IAM authorization documentation that helps users understand what privileges the service-linked role grants, but it does not fix or reference a specific vulnerability or incident.

Evidence

+  * `kms` – Allows Amazon Inspector to use select decryption actions to decrypt snapshots that are encrypted with AWS KMS customer managed keys.
