From 1.0.0 until 1.21.2, 1.22.2, and 1.23.1, Reader.Read in pkg/viaduct/pkg/packer trusts the 32-bit PackageHeader.PayloadLen received through the CloudHub viaduct message-processing path and allocates that amount of memory before validating an upper bound. An authenticated malicious or compromised edge peer can repeatedly send crafted headers with excessive declared lengths, causing memory exhaustion, CloudHub process termination or restart loops, and temporary disruption of cloud-edge communication. This issue does not provide unauthenticated access or direct code execution. This issue is fixed in versions 1.21.2, 1.22.2, and 1.23.1.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":6.5},"cwes":["CWE-789"],"references":["https://github.com/kubeedge/kubeedge/blob/master/CHANGELOG/CHANGELOG-1.21.md","https://github.com/kubeedge/kubeedge/blob/master/CHANGELOG/CHANGELOG-1.22.md","https://github.com/kubeedge/kubeedge/blob/master/CHANGELOG/CHANGELOG-1.23.md","https://github.com/kubeedge/kubeedge/commit/0fe1ea18e5d7fde29633286ddf1c7e71cb39606f","https://github.com/kubeedge/kubeedge/commit/725a73ca35a65d91aa6338e52b8faaab6058f528"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:55:23.253742848+00:00"},"epss":{"cve":"CVE-2026-62370","score":0.00504,"percentile":0.43111,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-gfw4-49f9-cp25","url":"https://osv.dev/vulnerability/GHSA-gfw4-49f9-cp25","summary":"KubeEdge: Unbounded allocation in viaduct packer enables authenticated remote DoS against CloudHub","modified":"2026-10-01T20:56:04.793505217Z","packages":[{"ecosystem":"Go","name":"github.com/kubeedge/kubeedge","purl":"pkg:golang/github.com/kubeedge/kubeedge","ranges":[">=1.0.0 <1.21.2"],"fixed":["1.21.2"]},{"ecosystem":"Go","name":"github.com/kubeedge/kubeedge","purl":"pkg:golang/github.com/kubeedge/kubeedge","ranges":[">=1.22.0 <1.22.2"],"fixed":["1.22.2"]},{"ecosystem":"Go","name":"github.com/kubeedge/kubeedge","purl":"pkg:golang/github.com/kubeedge/kubeedge","ranges":[">=1.23.0 <1.23.1"],"fixed":["1.23.1"]}]},{"id":"GO-2026-6569","url":"https://osv.dev/vulnerability/GO-2026-6569","summary":"KubeEdge: Unbounded allocation in viaduct packer enables authenticated remote DoS against CloudHub in github.com/kubeedge/kubeedge","modified":"2026-10-01T20:45:15.889308691Z","packages":[{"ecosystem":"Go","name":"github.com/kubeedge/kubeedge","purl":"pkg:golang/github.com/kubeedge/kubeedge","ranges":[">=1.0.0 <1.21.2",">=1.22.0 <1.22.2",">=1.23.0 <1.23.1"],"fixed":["1.21.2","1.22.2","1.23.1"]}]}],"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).
