CVE-2025-11935
WolfSSL TLS 1.3 PSK handling vulnerability: when a server answers a ClientHello with psk_dhe_ke and no key_share, the client may proceed with an authenticated PSK without PFS, degrading security. Connected sources indicate WolfSSL has addressed this in fixes across TLS 1.2/1.3 and PSK processing ...
