wolfssl: CVE-2022-23408

Severity: Medium
Source: [NVD] · [CVE record]
EPSS: 1.38% · Oct 25, 2026

wolfSSL 5.x before 5.1.1 uses non-random IV values in certain situations. This affects connections (without AEAD) using AES-CBC or DES3 with TLS 1.1 or 1.2 or DTLS 1.1 or 1.2. This occurs because of misplaced memory initialization in BuildMessage in internal.c.
