CVE-2026-3230
CVE-2026-3230 · Improper key_share validation in TLS 1.3 HelloRetryRequest
This page contains facts from public vulnerability sources. Check the original advisory before updating.
Missing required cryptographic step in the TLS 1.3 client HelloRetryRequest handshake logic in wolfSSL could lead to a compromise in the confidentiality of TLS-protected communications via a crafted HelloRetryRequest followed by a ServerHello message that omits the required key_share extension, resulting in derivation of predictable traffic secrets from (EC)DHE shared secret. This issue does not affect the client's authentication of the server during TLS handshakes.
