CVE-2026-10098
CVE-2026-10098 · OCSP CertID serial-number length-confusion in wolfSSL_OCSP_resp_find_status
This page contains facts from public vulnerability sources. Check the original advisory before updating.
OCSP CertID serial-number length-confusion in wolfSSL_OCSP_resp_find_status allows a same-issuer SingleResponse whose serial is a prefix of the target serial to be reported as the revocation status of a different certificate. The lookup compared serial-number bytes without first requiring the two serial numbers to be of equal length, so a SingleResponse for one certificate (same issuer) whose serial is a prefix of the target's serial would match, returning the wrong certificate's status. The fix requires the serial lengths to be equal before comparing the serial bytes.
