The underflow wraps a 16-bit length to a large value that is passed to AEAD decryption routines, causing heap buffer overflow and a crash. An unauthenticated attacker can trigger this remotely via malformed TLS Application Data records.","modified":"2026-07-18T00:02:19.774937545Z","published":"2026-07-14T21:41:35.775Z","upstream":["CVE-2026-1005","GHSA-2q9g-q8jj-fr53","EUVD-2026-13133"],"database_specific":{"sources":[{"url":"https://services.nvd.nist.gov/rest/json/cves/2.0?cveId=CVE-2026-1005","html_url":"https://nvd.nist.gov/vuln/detail/CVE-2026-1005","database_specific":{"status":"Analyzed"},"id":"CVE-2026-1005","imported":"2026-07-17T22:26:02.985Z","modified":"2026-06-17T10:14:51.830Z","published":"2026-03-19T17:16:21.873Z"},{"published":"2026-03-19T18:31:18Z","url":"https://api.github.com/advisories/GHSA-2q9g-q8jj-fr53","html_url":"https://github.com/advisories/GHSA-2q9g-q8jj-fr53","id":"GHSA-2q9g-q8jj-fr53","imported":"2026-07-17T22:26:03.157Z","modified":"2026-04-29T21:31:19Z"},{"imported":"2026-07-17T22:26:12.909Z","modified":"2026-03-19T17:20:03Z","published":"2026-03-19T17:00:10Z","url":"https://euvdservices.enisa.europa.eu/api/enisaid?id=EUVD-2026-13133","html_url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-13133","id":"EUVD-2026-13133"}],"license":"CC-BY-4.0"},"references":[{"type":"WEB","url":"https://github.com/advisories/GHSA-2q9g-q8jj-fr53"},{"type":"WEB","url":"https://github.com/wolfSSL/wolfssl/pull/9571"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-1005"}],"affected":[{"package":{"name":"wolfSSL_jll","ecosystem":"Julia","purl":"pkg:julia/wolfSSL_jll?uuid=98c43586-9870-5ae5-ab22-acc77b9bbdb5"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"5.9.2+0"}]}],"database_specific":{"source":"https://github.com/JuliaLang/SecurityAdvisories.jl/tree/generated/osv/2026/JLSEC-2026-692.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:P/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
