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.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N","score":6.9},"cvss_v3":null,"cwes":["CWE-400","CWE-770","CWE-834"],"references":["https://github.com/containerd/containerd/security/advisories/GHSA-pg57-6jwg-q645"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:56:02.509636177+00:00"},"epss":{"cve":"CVE-2026-53493","score":0.00356,"percentile":0.29375,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-pg57-6jwg-q645","url":"https://osv.dev/vulnerability/GHSA-pg57-6jwg-q645","summary":"Containerd has image-pull DoS via crafted OCI index graph amplification","modified":"2026-10-01T20:55:46.094271282Z","packages":[{"ecosystem":"Go","name":"github.com/containerd/containerd/v2","purl":"pkg:golang/github.com/containerd/containerd/v2","ranges":[">=2.0.0 <2.0.13"],"fixed":["2.0.13"]},{"ecosystem":"Go","name":"github.com/containerd/containerd","purl":"pkg:golang/github.com/containerd/containerd","ranges":["<1.7.36"],"fixed":["1.7.36"]},{"ecosystem":"Go","name":"github.com/containerd/containerd/v2","purl":"pkg:golang/github.com/containerd/containerd/v2","ranges":[">=2.1.0 <2.2.9"],"fixed":["2.2.9"]},{"ecosystem":"Go","name":"github.com/containerd/containerd/v2","purl":"pkg:golang/github.com/containerd/containerd/v2","ranges":[">=2.3.0 <2.3.6"],"fixed":["2.3.6"]},{"ecosystem":"Go","name":"github.com/containerd/containerd/v2","purl":"pkg:golang/github.com/containerd/containerd/v2","ranges":[">=2.4.0 <2.4.1"],"fixed":["2.4.1"]}]},{"id":"GO-2026-6597","url":"https://osv.dev/vulnerability/GO-2026-6597","summary":"Containerd has image-pull DoS via crafted OCI index graph amplification in github.com/containerd/containerd","modified":"2026-10-01T20:45:17.223140621Z","packages":[{"ecosystem":"Go","name":"github.com/containerd/containerd","purl":"pkg:golang/github.com/containerd/containerd","ranges":["<1.7.36"],"fixed":["1.7.36"]},{"ecosystem":"Go","name":"github.com/containerd/containerd/v2","purl":"pkg:golang/github.com/containerd/containerd/v2","ranges":[">=2.0.0 <2.0.13",">=2.1.0 <2.2.9",">=2.3.0 <2.3.6",">=2.4.0 <2.4.1"],"fixed":["2.0.13","2.2.9","2.3.6","2.4.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
