CVE-2026-94418 Signature failure masked by date error under WOLFSSL_SMALL_CERT_VERIFY

Under WOLFSSLSMALLCERTVERIFY, ProcessPeerCertParse runs the certificate signature check separately from the parse to keep peak memory down, then merges the two results, but it merged the signature result back only when the parse returned 0, so any parse error hid it. ParseCertRelative reaches its...

CVE-2026-94418

WolfSSL is vulnerable to a cryptographic signature verification bypass when the WOLFSSL_SMALL_CERT_VERIFY option is enabled. The ProcessPeerCertParse() function separates signature checks from parsing to save memory but fails to merge the signature result if a parse error occurs, effectively hidi...

CVE-2026-94419

The wolfSSL library (releases v5.3.0 through v5.9.2 ) is vulnerable to client session cache reference poisoning. Due to missing checks on the process-global SessionCache , an attacker can overwrite a client-side entry by providing a matching TLS 1.2 session ID sent in clear. This allows an attack...

CVE-2026-94419 Client session cache reference poisoning allows resumption with wrong server

Without NOSESSIONCACHEREF, wolfSSLgetsession does not return a session object but a ClientSession reference of the form row, index, hashsessionID into the process-global SessionCache, and ClientSessionToSession validates it against that hash alone. Because the TLS 1.2 session ID is chosen by the...
