CVE-2026-11316: dr_libs dr_wav out-of-bounds write in cue metadata parsing

CVE-2026-11316 · Severity: high · CVSS 8.8 · Published 2026-11-10

dr_libs is a popular audio decoding library used in games and embedded systems. A flaw in how it parses WAV file metadata allows an attacker to craft a malicious .wav file that writes beyond allocated memory boundaries, potentially causing the application to crash or enabling code execution when the compromised application processes the file.

Technologies: Mackron Dr Libs. Vendors: Mackron.

Technical details

The dr_wav WAV decoder contains an out-of-bounds write vulnerability (CWE-787) in the drwav__read_cue_to_metadata_obj function. The vulnerability occurs in a two-pass metadata parsing routine where pass 1 counts and reserves memory for recognized chunks, but pass 2 can advance the metadata cursor even when validation fails in smpl chunks, causing misalignment between reserved and written memory. An attacker providing a specially crafted WAV file with malformed metadata can trigger this flaw, leading to memory corruption.
