{"cve":"CVE-2022-31030","nvd":{"published":"2022-06-09T14:15:08.550","modified":"2026-06-17T04:44:38.587","status":"Modified","description":"containerd is an open source container runtime. A bug was found in the containerd's CRI implementation where programs inside a container can cause the containerd daemon to consume memory without bound during invocation of the `ExecSync` API. This can cause containerd to consume all available memory on the computer, denying service to other legitimate workloads. Kubernetes and crictl can both be configured to use containerd's CRI implementation; `ExecSync` may be used when running probes or when executing processes via an \"exec\" facility. This bug has been fixed in containerd 1.6.6 and 1.5.13. Users should update to these versions to resolve the issue. Users unable to upgrade should ensure that only trusted images and commands are used.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":["CWE-400"],"references":["http://www.openwall.com/lists/oss-security/2022/06/07/1","https://github.com/containerd/containerd/commit/c1bcabb4541930f643aa36a2b38655e131346382","https://github.com/containerd/containerd/security/advisories/GHSA-5ffw-gxpp-mxpf","https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/REOZCUAPCA7NFDWYBDYX6EYXWLHABKBO/","https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/WSIGDBHAB3I75JBJNGWEPBTJPS2FOVHD/"],"products":["debian:debian_linux","fedoraproject:fedora","linuxfoundation:containerd"],"source":"nvd","synced_at":"2026-10-19T21:32:39.174919249+00:00"},"epss":{"cve":"CVE-2022-31030","score":0.00387,"percentile":0.32798,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-5ffw-gxpp-mxpf","url":"https://osv.dev/vulnerability/GHSA-5ffw-gxpp-mxpf","summary":"containerd CRI plugin: Host memory exhaustion through ExecSync","modified":"2026-09-10T03:49:49.235350096Z","packages":[{"ecosystem":"Go","name":"github.com/containerd/containerd","purl":"pkg:golang/github.com/containerd/containerd","ranges":["<1.5.13"],"fixed":["1.5.13"]},{"ecosystem":"Go","name":"github.com/containerd/containerd","purl":"pkg:golang/github.com/containerd/containerd","ranges":[">=1.6.0 <1.6.6"],"fixed":["1.6.6"]}]},{"id":"GO-2022-0482","url":"https://osv.dev/vulnerability/GO-2022-0482","summary":"containerd CRI plugin: Host memory exhaustion through ExecSync in github.com/containerd/containerd","modified":"2026-02-04T04:07:30.567768Z","packages":[{"ecosystem":"Go","name":"github.com/containerd/containerd","purl":"pkg:golang/github.com/containerd/containerd","ranges":["<1.5.13",">=1.6.0 <1.6.6"],"fixed":["1.5.13","1.6.6"]}]}],"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).
