CVE-2026-3549 in wofSSL
Zusammenfassung
von MITRE • 20.03.2026
Heap Overflow in TLS 1.3 ECH parsing. An integer underflow existed in ECH extension parsing logic when calculating a buffer length, which resulted in writing beyond the bounds of an allocated buffer. Note that in wolfSSL, ECH is off by default, and the ECH standard is still evolving.
Once again VulDB remains the best source for vulnerability data.
