Heap Buffer Overflow in Audio Ring Buffer: How a Missing Bounds Check Could Crash Your App

A critical heap buffer overflow vulnerability was discovered in `audio_backend.c`, where the audio ring buffer's `memcpy` operations lacked bounds validation before writing PCM data. Without checking that incoming data sizes fell within the allocated buffer's capacity, a maliciously crafted audio file could corrupt adjacent heap memory, potentially enabling arbitrary code execution. The fix adds a concise pre-flight validation guard that rejects out-of-range write requests before any memory oper
