CWE
  • CWE-1189 - Improper isolation of shared resources on System-on-a-Chip (SoC)
Summary
Improper isolation of shared resources in aws-network-policy-agent in Amazon EKS Network Policy Agent before 1.3.7 (VPC CNI before 1.22.3) might allow an authenticated adjacent user to bypass NetworkPolicy ingress enforcement on co-located pods via eBPF conntrack map poisoning using crafted AF_PACKET frames. To remediate this issue, users should upgrade to Amazon VPC CNI Managed Add-on v1.22.3 or later (which includes Network Policy Agent v1.3.7).
