CVE-2026-1005

CVE-2026-1005 affects wolfSSL’s packet sniffer up to version 5.8.4. The root cause is an integer underflow: a 16‑bit length is wrapped to a large value and passed to AEAD decryption, causing a heap buffer overflow in the tls record processing path (ssl_DecodePacket). This yields a crash (denial o...
