[ CVE-2026-53493 · Published 25 Sep 2026 ]

Containerd has image-pull DoS via crafted OCI index graph amplification

CVSS 6.9 EPSS <1%Fix available

[ Description ]Official description

containerd is an open-source container runtime. Prior to versions 1.7.36, 2.0.13, 2.2.9, 2.3.6, and 2.4.1, a crafted OCI index graph can force very high CPU/memory usage during PullImage (before container start), causing long ContainerCreating stalls and, at larger sizes, node/runtime instability. Versions 1.7.36, 2.0.13, 2.2.9, 2.3.6, and 2.4.1 fix the issue.
