CVE-2026-1584 (GCVE-0-2026-1584)

Vulnerability from cvelistv5 – Published: 2026-04-09 18:00 – Updated: 2026-07-15 01:21

Title

Gnutls: gnutls: remote denial of service via crafted clienthello with invalid psk binder

Summary

A flaw was found in gnutls. A remote, unauthenticated attacker can exploit this vulnerability by sending a specially crafted ClientHello message with an invalid Pre-Shared Key (PSK) binder value during the TLS handshake. This can lead to a NULL pointer dereference, causing the server to crash and resulting in a remote Denial of Service (DoS) condition.

Severity

7.5 (High)
