SCA: security update for antrea.io/antrea (GHSA-qcmw-8mm4-4p28)

high Tenable Self-Hosted Container Security Plugin ID 439737

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2026-34992)

Solution

Update the antrea.io/antrea library and its related packages to version 1.11.0-alpha.0.0.20260225185322-738bad662b20 or later.
