CRE-2025-0095 High Impact: 9/10 Mitigation: 7/10	NATS Connection Exhaustion: Maximum Connections Exceeded	Detects NATS server connection exhaustion where the configured maximum connection limit is exceeded, preventing new clients from establishing connections. This represents a critical messaging infrastructure failure that can cause cascading outages across distributed systems.	Message Queue Problems	nats	NATS Connection Exhaustion Critical Infrastructure
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.
