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 affecting miniaudio up to version 0.11.25. It involves a heap out-of-bounds read caused by improper null termination in the WAV BEXT metadata parser's coding history field. Processing specially crafted WAV files can cause the application to read beyond allocated memory, resulting in crashes or denial of service. The vulnerability is tracked under CWE-170 (Improper Null Termination). Fixes exist in specific commits (1df46ae) but no formal patched version number is stated in the provided data.
Potential Impact
Successful exploitation of this vulnerability can cause application crashes or denial of service due to out-of-bounds memory reads. There is no indication of code execution or data corruption beyond denial of service. No known exploits in the wild have been reported.
Mitigation Recommendations
A fix is available as indicated by the referenced commits (1df46ae), though no official patched version number is provided in this data. Users should update to a version including these commits once available. Until then, avoid processing untrusted WAV files with vulnerable versions of miniaudio. Patch status is not yet confirmed in formal releases — check the vendor repository or advisory for current remediation guidance.
