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...

CVE-2026-55961 wolfSSL_PKCS7_verify() reports success for degenerate (certs-only) PKCS#7 with no signer

wolfSSLPKCS7verify returning success for a degenerate certs-only PKCS7 object that contains no signer. Such an object has empty signerInfos, so the underlying signed-data verification succeeds without authenticating any content. The compatibility-layer verify path now rejects the object when no...

Improper Certificate Validation

Overview Affected versions of this package are vulnerable to Improper Certificate Validation in the wolfSSLX509verifycert function. An attacker can bypass certificate signature validation by supplying a certificate chain where an untrusted intermediate with Basic Constraints set to CA:FALSE is...

DEBIAN-CVE-2026-5501

wolfSSLX509verifycert in the OpenSSL compatibility layer accepts a certificate chain in which the leaf's signature is not checked, if the attacker supplies an untrusted intermediate with Basic Constraints CA:FALSE that is legitimately signed by a trusted root. An attacker who obtains any leaf...
