This integer overflow will result in a Use-After-Free for the buffer tokens, which can be filled with arbitrary malicious data after the free. This allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via crafted input.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","score":7.8},"cwes":["CWE-190","CWE-416"],"references":["https://github.com/radareorg/radare2/issues/15543","https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/WRQXCOVFWZIIMAZIAAFAVQGZOS7LGHXP/","https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/YQTOWEDFXDTGTD6D4NHRB4FUURQSTTEN/","https://github.com/radareorg/radare2/issues/15543","https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/WRQXCOVFWZIIMAZIAAFAVQGZOS7LGHXP/"],"products":["radare:radare2"],"source":"nvd","synced_at":"2026-10-19T20:59:27.069234358+00:00"},"epss":{"cve":"CVE-2019-19590","score":0.02536,"percentile":0.84946,"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).
