Summary

Expanded EC2FastLaunchFullAccess policy permissions to include Create/Modify Launch Template operations, network/SG resource management, and CloudFormation stack operations. Added EC2FastLaunchServiceRolePolicy permissions for EventBridge, CloudFormation, License Manager, KMS grants, and launch template deletion.

Security assessment

The changes document expanded IAM policy permissions for EC2 Fast Launch features. While they involve security-sensitive actions like managing security groups, KMS grants, and network resources, there's no evidence these changes address a specific vulnerability. The updates appear to reflect new feature capabilities rather than patching security flaws.
