CVE-2026-32837: CWE-170 Improper null termination in mackron miniaudio
miniaudio version 0.11.25 and earlier (fixed in commits 1df46ae and 1df46ae) contain a heap out-of-bounds read vulnerability in the WAV BEXT metadata parser that allows attackers to trigger memory access violations by processing crafted WAV files. Attackers can exploit improper null-termination handling in the coding history field to cause out-of-bounds reads past the allocated metadata pool, resulting in application crashes or denial of service.
AI Analysis
Technical Summary
CVE-2026-32837 is a medium severity vulnerability (CVSS 5.1) affecting mackron's miniaudio library up to version 0.11.25. The flaw is a heap out-of-bounds read caused by improper null termination in the WAV BEXT metadata parser, specifically in the coding history field. When processing crafted WAV files, this improper handling allows reading beyond allocated memory, potentially causing memory access violations and application crashes. The vulnerability is categorized under CWE-170 (Improper Null Termination). There are no known exploits in the wild and no cloud service is involved.
Potential Impact
Successful exploitation can cause application crashes or denial of service due to out-of-bounds memory reads. There is no indication of privilege escalation, code execution, or data disclosure from the provided information.
Mitigation Recommendations
No official patch or fix links are provided in the available data. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, avoid processing untrusted or specially crafted WAV files with affected versions of miniaudio to mitigate risk.
