CVE-2026-34992 Â (opens in a new tab)How to fix?
Upgrade github.com/antrea-io/antrea/pkg/agent/controller/noderoute to version 2.4.5, 2.5.2 or higher.
Overview
Affected versions of this package are vulnerable to Missing Encryption of Sensitive Data in the handling of inter-Node Pod traffic when dual-stack networking is configured with IPsec encryption enabled. An attacker can intercept and read sensitive IPv6 Pod traffic by monitoring network communications between nodes, as this traffic is transmitted in plaintext without encryption.
Note: This is only exploitable if the cluster is configured for dual-stack networking with IPsec enabled and IPv6 Pod traffic is present.
Workaround
This vulnerability can be mitigated by using WireGuard for inter-Node Pod traffic encryption, as WireGuard support does not suffer from this issue.
