CVE-2026-34992

Missing Encryption of Sensitive Data in antrea.io/antrea

Antrea is a Kubernetes networking solution intended to be Kubernetes native. Prior to 2.4.5 and 2.5.2, a missing encryption vulnerability affects inter-Node Pod traffic. In Antrea clusters configured for dual-stack networking with IPsec encryption enabled (trafficEncryptionMode: ipsec), Antrea fails to apply encryption for IPv6 Pod traffic. While the IPv4 traffic is correctly encrypted via ESP (Encapsulating Security Payload), traffic using IPv6 is transmitted in plaintext. This occurs because the packets are encapsulated (using Geneve or VXLAN) but bypass the IPsec encryption layer. Impacted Users: users with dual-stack clusters and IPsec encryption enabled. Single-stack IPv4 or IPv6 clusters are not affected. This vulnerability is fixed in 2.4.5 and 2.5.2.
