CVE-2026-94417

The wolfSSL library (all versions from 5.9.2 and earlier ) is vulnerable to a certificate revocation bypass when both OCSP and CRL checking are enabled. The flaw exists in ProcessPeerCerts() , where a soft-fail policy for missing OCSP responders causes the system to skip CRL checks for peer certi...
