Gnutls: gnutls: security bypass allows acceptance of revoked server certificates via crafted ocsp response_CVE-2026-3832

{
    "lastseen": "",
    "description": "A flaw was found in gnutls. A remote attacker could exploit this vulnerability by presenting a specially crafted Online Certificate Status Protocol (OCSP) response during a TLS handshake. Due to a logic error in how gnutls processes multi-record OCSP responses, a client with OCSP verification enabled may incorrectly accept a revoked server certificate, potentially leading to a compromise of trust.",
