Description

An issue in the ConfirmNameConstraints() function (wolfcrypt/src/asn.c) of wolfSSL v5.9.1 and v5.9.2 allows attackers to cause a Denial of Service (DoS) via providing crafted Certificate Authority certificates, leading to valid certificates without SAN to be incorrectly rejected by wolfSSL-based TLS clients.

Technical Analysis

CVE-2026-95208 is a denial of service vulnerability in the ConfirmNameConstraints() function located in wolfcrypt/src/asn.c of wolfSSL versions 5.9.1 and 5.9.2. The flaw allows attackers to cause TLS clients using wolfSSL to incorrectly reject valid certificates that lack Subject Alternative Names (SAN) by supplying specially crafted Certificate Authority certificates. This leads to a denial of service condition in affected TLS clients.

Potential Impact

Attackers can cause a denial of service by making wolfSSL-based TLS clients reject valid certificates without SAN, disrupting normal TLS connections that rely on these certificates.
