HIGHCVE-2026-56862

Handshake messages, such as KeyUpdate, are always considered as state-advancing, regardless of whether a handshake has been completed or not. As a result, a malicious client can keep sending KeyUpdate messages to force the server to keep performing key derivation operations indefinitely.

Affected: >=0, <1.25.13, >=1.26.0-0, <1.26.6, >=1.27.0-0, <1.27.0-rc.3
