Published Aug 5, 2026CWE-190EPSS 0.17%

Overview

CVE-2026-71261 is a high-severity vulnerability. It was published on August 5, 2026 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical description

dr_libs dr_wav.h (all versions through current master) contains an integer overflow in W64 CUE chunk metadata parsing. 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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
