Pull request overview
Adds a bounds check to prevent overrunning key->pubkey_raw when importing an X9.63 public key under the WOLFSSL_KCAPI_ECC build configuration (fix for zd#21356).
Changes:
- Guard
XMEMCPY(key->pubkey_raw, ...)with a length check for the KCAPI ECC case. - Return an error when the provided public key blob is larger than the destination buffer.
