Name of the Vulnerable Software and Affected Versions wolfSSL versions configured with --enable-aria and the proprietary MagicCrypto SDK

Description wolfSSL, when configured with --enable-aria and the proprietary MagicCrypto SDK, reuses an identical 12-byte GCM nonce for every application-data record in ARIA-GCM cipher suites used in TLS 1.2 and DTLS 1.2. This occurs because the wc AriaEncrypt function is stateless and passes the caller-supplied IV verbatim to the MagicCrypto SDK without an internal counter, and the explicit IV is zero-initialized at session setup and never incremented in non-FIPS builds. AES-GCM is not affected as wc AesGcmEncrypt ex maintains an internal invocation counter.

Recommendations wolfSSL versions configured with --enable-aria and the proprietary MagicCrypto SDK should be updated when a fix is available.
