CVE-2026-3832

LOW

3.7

CVSS v3

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.

Common questions

How do I fix CVE-2026-3832?

Published advisories record a fix for 36 affected products. The "How to fix" section on this page lists the fixed version and source advisory for each one, so apply the entry matching what you actually run.

Is CVE-2026-3832 being actively exploited?

Not that we know of. CVE-2026-3832 is not in the CISA Known Exploited Vulnerabilities catalog. Its EPSS score of 0.72% is the estimated probability that it will be exploited in the next 30 days. That is higher than 50% of all scored CVEs.

How severe is CVE-2026-3832?

CVE-2026-3832 has a CVSS v3 base score of 3.7, rated low. CVSS rates the technical impact if the vulnerability is exploited, not how likely that is, so weigh it alongside the exploit-prediction score when you decide what to patch first.

What does CVE-2026-3832 affect?

Published advisories record a fix for gnutls28 (Debian), gnutls (Rocky), gnutls (Red Hat / RHEL), gnutls-c++ (Red Hat / RHEL), and 32 more. Only products with a sourced advisory are listed, so treat this as what we can cite rather than a complete inventory.
