EchelonGraph scoreMEDIUM confidence

This low-severity CVE scores 1.0 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.1%, top 96% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

Exporting a TPM based RSA key larger than 2048 bits from the TPM could overrun a stack buffer if the default MAX_RSA_KEY_BITS=2048 is used. If your TPM 2.0 module supports RSA key sizes larger than 2048 bit and your applications supports creating or importing an RSA private or public key larger than 2048 bits and your application calls wolfTPM2_RsaKey_TpmToWolf on that key, then a stack buffer could be overrun. If the MAX_RSA_KEY_BITS build-time macro is set correctly (RSA bits match what TPM hardware is capable of) for the hardware target, then a stack overrun is not possible.
