CVE-2026-56862 is a high-severity vulnerability in Kubernetes where handshake messages like KeyUpdate are always treated as state-advancing, even if the handshake has not completed. This behavior affects multiple Kubernetes package versions prior to 1.34.13-r2 and 4.1.6-r1. The flaw can cause denial of service by disrupting the expected handshake state management.
