CVE-2026-47262Network attack vector

Runtime crash via unbounded image group parsing

Published Jul 1, 2026 · Updated Jul 1, 2026

Uncontrolled resource consumption in affected containerd releases allows attackers to crash the runtime with a crafted container image. During container creation, unbounded parsing of attacker-controlled group-file entries allocates memory until the containerd process is OOM-killed. Attackers must be able to import an image or schedule a pod; exploitation takes the runtime API offline and disrupts Docker Engine or Kubernetes clients.
