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 the parsing of W64 CUE chunk metadata, leading to potential buffer overflows and code execution.","exploitability":"Exploitation is moderately difficult requiring a 32-bit build environment and specific input to trigger the overflow.","blast_radius":"If exploited, this could lead to remote code execution, allowing attackers to gain full control over affected systems.","remediation":"Disable the affected feature or upgrade to the latest version of dr_libs and dr_wav.h.","detection":"No reliable host or network indicator is derivable from the published description.","tags":["buffer-overflow","code-execution","32-bit"],"model":"qwen2.5:7b-instruct","analyzedAt":"2026-10-09T08:44:59.296Z"}}
