A zero-length payload causes an integer underflow in the uint8_t filter order calculation, which wraps to 255 and is clamped to 10, causing the function to unconditionally read 11 bytes from a zero-byte buffer, resulting in media process termination or silent consumption of adjacent heap memory as reflection coefficients."
