CVE-2026-32836
Last modified
CVE-2026-32836 is a medium-severity vulnerability rated 6.9/10 on the CVSS scale. dr_libs dr_flac.h version 0.13.3 and earlier (fixed in commits fefced4, 4f5a4cd, and 663239a) contain an uncontrolled memory allocation vulnerability in drflac__read_and_decode_metadata() that allows attackers to trigger excessive memory allocation by supplying crafted PICTURE metadata blocks. Attackers can exploit attacker-controlled mimeLength and descriptionLength fields to cause denial of service through memory exhaustion when processing FLAC streams with metadata callbacks.. EPSS estimates a 0.18% chance of exploitation in the next 30 days.
