In drwav__metadata_process_chunk, a stage-1 capacity estimate truncates the 64-bit W64 chunk sizeInBytes to size_t before dividing by DRWAV_CUE_POINT_BYTES; on 32-bit builds this truncation causes the pre-allocated extra metadata capacity to be computed incorrectly.","cvssScore":7.8,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","cwes":["CWE-190"],"vendors":[],"products":[],"references":[{"url":"https://github.com/mackron/dr_libs","tags":[]},{"url":"https://github.com/mackron/dr_libs/blob/master/dr_wav.h","tags":[]}],"exploitRefs":[{"url":"https://github.com/mackron/dr_libs","tags":[]},{"url":"https://github.com/mackron/dr_libs/blob/master/dr_wav.h","tags":[]}],"hasPoc":true,"ai":{"summary":"The flaw involves an integer overflow in W64 CUE chunk metadata parsing within dr_libs dr_wav.h, leading to potential buffer overflows and data corruption.","exploitability":"Exploitation requires access to process memory and specific conditions on the build environment; it is moderately difficult given these constraints.","blast_radius":"If exploited, this could lead to severe system instability or remote code execution, depending on the application's context.","remediation":"Update to a patched version of dr_libs or apply a custom fix that ensures proper handling of chunk sizes.","tags":["buffer-overflow","data-corruption","memory"],"model":"qwen2.5:7b-instruct","analyzedAt":"2026-08-11T06:52:54.762Z"}}
