CVE-2026-3832 (GCVE-0-2026-3832)

Vulnerability from cvelistv5 – Published: 2026-04-30 17:41 – Updated: 2026-09-01 12:10

Title

Gnutls: gnutls: security bypass allows acceptance of revoked server certificates via crafted ocsp response

Summary

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.

Severity

gnutls: Fix crashing on an underflow with a DTLS datagram (CVE-2026-33845)
gnutls: Fix RSA-PSK identity truncation (CVE-2026-42010)
gnutls: Fix case-sensitivity of domain name comparison in name constraints (CVE-2026-3833)
gnutls: Fix intersecting empty name constraints (CVE-2026-42011)
gnutls: Denial of Service via heap buffer overflow in DTLS handshake fragment reassembly (CVE-2026-33846)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
