CVE-2026-3832

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.

This issue has a LOW impact. A flaw in gnutls' OCSP stapling implementation allows a client with OCSP verification enabled to accept a revoked server certificate. This occurs when a multi-record OCSP response is stapled, and the client incorrectly reads the certificate status from an unrelated record, leading to an order-dependent acceptance of a revoked certificate.
