{"cve":"CVE-2025-47291","nvd":{"published":"2025-05-21T18:15:52.853","modified":"2026-06-17T09:27:40.750","status":"Analyzed","description":"containerd is an open-source container runtime. A bug was found in the containerd's CRI implementation where containerd, starting in version 2.0.1 and prior to version 2.0.5, doesn't put usernamespaced containers under the Kubernetes' cgroup hierarchy, therefore some Kubernetes limits are not honored. This may cause a denial of service of the Kubernetes node. This bug has been fixed in containerd 2.0.5+ and 2.1.0+. Users should update to these versions to resolve the issue. As a workaround, disable usernamespaced pods in Kubernetes temporarily.","cvss_v4":{"vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U","score":4.6},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-266"],"references":["https://github.com/containerd/containerd/security/advisories/GHSA-cxfp-7pvr-95ff"],"products":["linuxfoundation:containerd"],"source":"nvd","synced_at":"2026-10-19T22:01:57.636215869+00:00"},"epss":{"cve":"CVE-2025-47291","score":0.0029,"percentile":0.21628,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-cxfp-7pvr-95ff","url":"https://osv.dev/vulnerability/GHSA-cxfp-7pvr-95ff","summary":"containerd CRI plugin: Incorrect cgroup hierarchy assignment for containers running in usernamespaced Kubernetes pods.","modified":"2026-09-10T03:50:24.594674595Z","packages":[{"ecosystem":"Go","name":"github.com/containerd/containerd/v2","purl":"pkg:golang/github.com/containerd/containerd/v2","ranges":[">=2.0.1 <2.0.5"],"fixed":["2.0.5"]}]},{"id":"GO-2025-3701","url":"https://osv.dev/vulnerability/GO-2025-3701","summary":"Incorrect cgroup assignment for containers running in usernamespaced Kubernetes pods in github.com/containerd/containerd","modified":"2026-02-04T02:40:32.981028Z","packages":[{"ecosystem":"Go","name":"github.com/containerd/containerd/v2","purl":"pkg:golang/github.com/containerd/containerd/v2","ranges":[">=2.0.1 <2.0.5"],"fixed":["2.0.5"]}]}],"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).
