CVE-2026-29022: dr_libs dr_wav.h heap buffer overflow in drwav__read_smpl_to_metadata_obj

CVE-2026-29022 · Severity: high · CVSS 7.3 · Published 2026-03-03

dr_wav is a popular C library used by developers to decode and process WAV audio files in various applications. A security flaw in how the library handles metadata allows a specially crafted audio file to corrupt the computer's memory. If a user opens a malicious WAV file with an application using this library, it could lead to a program crash or potentially allow an attacker to take control of the system.

Technical details

A heap-based buffer overflow exists in dr_wav.h within the drwav__read_smpl_to_metadata_obj() function. The vulnerability stems from a logic mismatch in a two-pass metadata parser: pass 1 validates the 'sampleLoopCount' field to determine allocation size, but pass 2 processes 'smpl' chunks unconditionally. By providing a crafted WAV file where these passes disagree, an attacker can trigger an out-of-bounds write of 36 bytes of controlled data. This is reachable via any drwav_init_*_with_metadata() call. The issue was fixed in commit 8a7258c (released as version 0.14.5).
