CVE-2026-32837Public exploit

Application crash via unterminated BEXT coding history

Published Mar 17, 2026 · Updated Mar 17, 2026

Heap out-of-bounds read in the WAV BEXT metadata parser in miniaudio 0.11.25 and earlier allows attackers to crash applications. The ma_dr_wav__read_bext_to_metadata_obj function reserves a terminator byte but leaves it unwritten before ma_dr_wav__strlen scans the heap without a bound. Exploitation requires an application to parse a crafted WAV file with metadata enabled and interrupts that application through a memory-access crash.
