CRE-2025-0088 High Impact: 9/10 Mitigation: 8/10	NATS JetStream Storage Exhaustion Detection	Detects NATS JetStream storage exhaustion conditions when streams reach configured storage limits (maximum bytes, maximum messages) causing message storage failures. These patterns indicate insufficient stream storage capacity relative to message production rate, leading to message rejection and potential data loss.

CRE-2025-0112 Critical Impact: 10/10 Mitigation: 4/10	AWS VPC CNI Node IP Pool Depletion Crisis	Critical AWS VPC CNI node IP pool depletion detected causing cascading pod scheduling failures. This pattern indicates severe subnet IP address exhaustion combined with ENI allocation failures, leading to complete cluster networking breakdown. The failure sequence shows ipamd errors, kubelet scheduling failures, and controller-level pod creation blocks that render clusters unable to deploy new workloads, scale existing services, or recover from node failures. This represents one of the most severe Kubernetes infrastructure failures, often requiring immediate manual intervention including subnet expansion, secondary CIDR provisioning, or emergency workload termination to restore cluster functionality.
