| CRE-2025-0061 Medium Impact: 7/10 Mitigation: 4/10 | Karpenter Stability Issues on EKS During Leader Election | - EKS may be able to handle steady, predictable scale, but struggles during large‑scale auto scaling events when many workloads and nodes are spinning up or down simultaneously. - This instability affects components that implement leader election using the Kubernetes API, such as: - aws‑load‑balancer‑controller - karpenter - keda‑operator - ebs‑csi‑controller - efs‑csi‑controller | Stability Problems | karpenter | KarpenterKEDAAWSEKS |
