Denial of Service in containerd via crafted container image memory exhaustion
CVE-2026-47262 is a denial-of-service vulnerability in containerd's image-handling path. A maliciously crafted container image can trigger uncontrolled memory consumption during container creation, described in the advisory as image-triggered DoS caused by unbounded group parsing. When the affected containerd instance processes the crafted image, memory exhaustion can occur and the containerd process may be terminated by the operating system's out-of-memory killer. This causes the container runtime API to become unavailable and disrupts higher-level consumers such as Docker Engine and Kubernetes control-plane components on the affected node.
