Live › vulnerability › CVE-2026-62370
Go to dashboardKubeEdge's viaduct packer trusts a 32-bit payload length from incoming CloudHub messages and allocates that much memory before checking a limit. An authenticated edge peer can send crafted headers to exhaust cloud memory, crash CloudHub, and disrupt cloud-edge communication.
Summary written from the sources below. Check the originals before acting.

| Product | Ecosystem | Affected | Fixed in |
|---|---|---|---|
| github.com/kubeedge/kubeedge | go | >= 1.23.0, < 1.23.1 | 1.21.2, 1.22.2, 1.23.1 |
Check the go.mod of your KubeEdge build for github.com/kubeedge/kubeedge version between 1.23.0 and 1.23.1 (or any 1.0.0 to 1.21.1 / 1.22.0 to 1.22.1 build)
Run: go list -m github.com/kubeedge/kubeedge in the module that builds CloudHub
Upgrade to KubeEdge 1.21.2, 1.22.2, or 1.23.1 (whichever matches your release line) and redeploy CloudHub
Each row is the first time that source carried this signal. The analyst’s rows are its own findings.
KubeEdge is an open source system for extending native containerized application orchestration capabilities to hosts at Edge. 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.
