CVE-2026-55964

Chain intermediate CA:TRUE without keyCertSign accepted as a signing CA. Intermediate CA certificates are required to have the keyCertSign key usage when a Key Usage extension is present, but chain-supplied temporary CAs WOLFSSLTEMPCA added while building a certificate path were previously exempt...

UBUNTU-CVE-2026-55960

Un-negotiated Raw Public Key RFC 7250 accepted in place of an X.509 certificate, bypassing chain validation. A raw public key has no chain, so ParseCertRelative accepts it without performing any trust verification; it must therefore only be accepted when RPK was actually negotiated for that peer...

CVE-2026-6731 X.509 name constraint bypass via Subject CN treated as a DNS name

X.509 name constraint bypass via the Subject Common Name when treated as a DNS-type name. A certificate whose Subject CN violates an issuing CA's DNS name constraints could be accepted...

CVE-2026-6731

CVE-2026-6731 describes an X.509 name constraint bypass where the Subject CN is treated as a DNS-type name, allowing a certificate to pass DNS constraints if the CN violates them. Public sources (NVD and related feeds) reference this bypass and provide CVSS metrics (v3.1: 7.5, Network, High impac...

CVE-2026-11310

The CVE-2026-11310 entry concerns wolfSSL’s X509_verify_cert() when built with --enable-opensslextra (OPENSSL_EXTRA) and used by applications that pass untrusted intermediates to X509_verify_cert(). The root cause is that wolfSSL temporarily loads untrusted intermediates into the certificate mana...

CVE-2026-11310 X.509 trust-chain bypass in wolfSSL_X509_verify_cert() via untrusted intermediate anchoring

X.509 trust-chain bypass in the OpenSSL compatibility certificate verifier wolfSSLX509verifycert. This affects only builds with --enable-opensslextra OPENSSLEXTRA and whose application validates certificates by calling X509verifycert with caller-supplied untrusted intermediate certificates; for...

crypto/x509: golang: golang crypto/x509: Denial of Service via excessive processing of DNS SAN entries

A flaw was found in the crypto/x509 package of golang. This vulnerability allows a remote attacker to cause a Denial of Service DoS by presenting a specially crafted X.509 certificate with a large number of DNS Subject Alternative Name SAN entries. The certificate verification process, specifical...

CVE-2026-11999

X.509 trust-chain bypass path-depth exhaustion in the OpenSSL compatibility certificate verifier wolfSSLX509verifycert. This affects only builds with --enable-opensslextra whose application calls X509verifycert with caller-supplied untrusted intermediates; for those users it is critical, otherwis...

crypto/x509: golang: Denial of Service due to excessive resource consumption via crafted certificate

A flaw was found in golang. A remote attacker could exploit this vulnerability by providing a specially crafted certificate during the error string construction process within the HostnameError.Error function. This flaw, caused by unbounded string concatenation, leads to excessive resource...

crypto/x509: golang: Go crypto/x509: Denial of Service via inefficient certificate chain validation

A flaw was found in Go's crypto/x509 package. A remote attacker could exploit this by presenting a specially crafted certificate chain containing a large number of policy mappings. This inefficient validation process consumes excessive resources, which can lead to a denial of service DoS for...
