CVE-2025-7844 wolfTPM library wrapper function `wolfTPM2_RsaKey_TpmToWolf` copies external data to a fixed-size stack buffer without length validation potentially causing stack-based buffer overflow

Exporting a TPM based RSA key larger than 2048 bits from the TPM could overrun a stack buffer if the default MAXRSAKEYBITS=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...

CVE-2025-7844

CVE-2025-7844 affects wolfTPM (wolfSSL) via wolfTPM2_RsaKey_TpmToWolf: exporting an RSA key >2048 bits from a TPM can overflow a fixed-size stack buffer when MAX_RSA_KEY_BITS is 2048. Root cause: copying external data to a stack buffer without length validation. If MAX_RSA_KEY_BITS matches the...
