{"id":"CVE-2022-23471","aliases":["GHSA-2qjp-425j-52j9","GO-2022-1147"],"url":"https://o3.security/vulnerability/CVE-2022-23471","summary":"containerd CRI stream server: Host memory exhaustion through terminal resize goroutine leak","details":"### Impact\n\nA bug was found in containerd's CRI implementation where a user can exhaust memory on the host. In the CRI stream server, a goroutine is launched to handle terminal resize events if a TTY is requested. If the user's process fails to launch due to, for example, a faulty command, the goroutine will be stuck waiting to send without a receiver, resulting in a memory leak. Kubernetes and crictl can both be configured to use containerd's CRI implementation and the stream server is used for handling container IO.\n\n### Patches\n\nThis bug has been fixed in containerd 1.6.12 and 1.5.16.  Users should update to these versions to resolve the issue.\n\n### Workarounds\n\nEnsure that only trusted images and commands are used and that only trusted users have permissions to execute commands in running containers. \n\n### For more information\n\nIf you have any questions or comments about this advisory:\n\n* Open an issue in [containerd](https://github.com/containerd/containerd/issues/new/choose)\n* Email us at [security@containerd.io](mailto:security@containerd.io)\n\nTo report a security issue in containerd:\n* [Report a new vulnerability](https://github.com/containerd/containerd/security/advisories/new)\n* Email us at [security@containerd.io](mailto:security@containerd.io)","published":"2022-12-07T22:51:34.193Z","modified":"2026-08-12T03:51:41.520887259Z","cvss":{"score":5.7,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:N/I:N/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/containerd/containerd","fixedVersion":"1.5.16"},{"ecosystem":"Go","name":"github.com/containerd/containerd","fixedVersion":"1.6.12"}],"fix":{"url":"https://github.com/containerd/containerd/commit/a05d175400b1145e5e6a735a6710579d181e7fb0","label":"containerd/containerd@a05d175"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/23xxx/CVE-2022-23471.json"},{"type":"ADVISORY","url":"https://github.com/containerd/containerd/security/advisories/GHSA-2qjp-425j-52j9"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-23471"},{"type":"ADVISORY","url":"https://security.gentoo.org/glsa/202401-31"},{"type":"FIX","url":"https://github.com/containerd/containerd/commit/a05d175400b1145e5e6a735a6710579d181e7fb0"},{"type":"WEB","url":"https://github.com/containerd/containerd/commit/241563be06a3de8b6a849414c4e805b68d3bb295"},{"type":"PACKAGE","url":"https://github.com/containerd/containerd"},{"type":"WEB","url":"https://github.com/containerd/containerd/releases/tag/v1.5.16"},{"type":"WEB","url":"https://github.com/containerd/containerd/releases/tag/v1.6.12"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:41.520887259Z"}}
