🚨 CVE-2026-95208
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. NOTE: this is disputed by multiple parties because the behavior does not offer a new ability for an adversary to conduct a denial of service, and because the product can reasonably choose to enforce a dNSName constraint against Common Name when Subject Alternative Name is absent.
