CWE: CWE-190 \u2014 Integer Overflow or Wraparound
The product performs a calculation that can produce an integer overflow or wraparound, when the logic assumes that the resulting value will always be larger than the original value. This can introduce other weaknesses when the calculation is used for resource management or execution control.

Code:
void md_map_sh384(uint8_t *hash, const uint8_t *msg, int len) {
	SHA384Context ctx;

	if (SHA384Reset(&ctx) != shaSuccess) {
		RLC_THROW(ERR_NO_VALID);
		return;
	}
	if (SHA384Input(&ctx, msg, len) != shaSuccess) {
		RLC_THROW(ERR_NO_VALID);
		return;
	}
	if (SHA384Result(&ctx, hash) != shaSuccess) {
		RLC_THROW(ERR_NO_VALID);
		return;
	}
}
