CVE-2026-53493

CVE-2026-53493 · Containerd has image-pull DoS via crafted OCI index graph amplification

This page contains facts from public vulnerability sources. Check the original advisory before updating.

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.
