URI nameConstraints from constrained intermediate CAs are parsed but not enforced during certificate chain verification in wolfcrypt/src/asn.c. A compromised or malicious sub-CA could issue leaf certificates with URI SAN entries that violate the nameConstraints of the issuing CA, and wolfSSL woul...
CVE-2026-42765
A flaw was found in OpenSSL. When an application is configured with specific non-default settings for certificate verification, including both Online Certificate Status Protocol OCSP response checking and partial chain verification, a NULL dereference can occur. This vulnerability can be triggere...

DEBIAN-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...
EUVD-2026-39486
Partial-chain certificate verification may accept chains that terminate at a peer-supplied, untrusted intermediate certificate rather than a trusted anchor. An attacker could present a chain that ends at an intermediate they control and have it accepted as valid. This affects the OpenSSL...
