Attackers can exploit attacker-controlled mimeLength and descriptionLength fields to cause denial of service through memory exhaustion when processing FLAC streams with metadata callbacks.","cvss_v4":{"vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","score":6.9},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":6.2},"cwes":["CWE-789"],"references":["https://github.com/mackron/dr_libs/commit/4f5a4cd3b57564d969443c580c75857e039f100a","https://github.com/mackron/dr_libs/commit/663239a3d0460c33bd5b6e5166edcb404e3df676","https://github.com/mackron/dr_libs/commit/fefced4a64adfb1a68a2d31d882366e56096dee8","https://github.com/mackron/dr_libs/issues/298","https://www.vulncheck.com/advisories/mackron-dr-libs-excessive-memory-allocation-in-picture-metadata-parsing"],"products":["mackron:dr_libs"],"source":"nvd","synced_at":"2026-10-19T22:26:19.218427112+00:00"},"epss":{"cve":"CVE-2026-32836","score":0.0019,"percentile":0.08735,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
