Unsafe fixed-size memcpy operation in AudioBuffer::writeSpace() of schreibfaul1 ESP32-audioI2S 3.4.5 allows remote heap buffer overflow. The code copies a full UINT16_MAX bytes without validating destination available space, causing out-of-bounds memory write.
Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
