Unchecked unsigned integer overflow in buffer size calculation in schreibfaul1 ESP32-audioI2S 3.4.5 leads to undersized PSRAM buffer allocation. Subsequent normal audio buffer read and write operations cause heap out-of-bounds access, memory corruption, denial of service, and potential code execution.
