Type Values Removed Values Added
Description Missing mutex synchronization in AudioBuffer::freeSpace() in schreibfaul1 ESP32-audioI2S 3.4.5 creates a race condition between concurrent tasks. The function calculates available buffer space without protecting shared read/write pointers, returning an incorrectly large value. Trusting this value leads to heap out-of-bounds write, memory corruption, device crash, and arbitrary code execution. DO NOT USE THIS CVE RECORD. ConsultIDs: none. Reason: This record was withdrawn by its CNA. Further investigation showed that it was not a security issue. Notes: none.
