When deserializing session data with SESSION_CERTS enabled, certificate and session id lengths are read from an untrusted input without bounds validation, allowing an attacker to overflow fixed-size buffers and corrupt heap memory. A maliciously crafted session would need to be loaded from an external source to trigger this vulnerability. Internal sessions were not vulnerable.","modified":"2026-07-18T00:02:20.923008737Z","published":"2026-07-14T21:41:35.775Z","upstream":["CVE-2026-2646","GHSA-24vq-qfc5-qrmj","EUVD-2026-13137"],"database_specific":{"license":"CC-BY-4.0","sources":[{"published":"2026-03-19T18:16:22.223Z","url":"https://services.nvd.nist.gov/rest/json/cves/2.0?cveId=CVE-2026-2646","html_url":"https://nvd.nist.gov/vuln/detail/CVE-2026-2646","database_specific":{"status":"Analyzed"},"id":"CVE-2026-2646","imported":"2026-07-17T22:27:48.628Z","modified":"2026-06-17T10:31:27.500Z"},{"published":"2026-03-19T18:31:19Z","url":"https://api.github.com/advisories/GHSA-24vq-qfc5-qrmj","html_url":"https://github.com/advisories/GHSA-24vq-qfc5-qrmj","id":"GHSA-24vq-qfc5-qrmj","imported":"2026-07-17T22:27:48.795Z","modified":"2026-04-29T21:31:20Z"},{"modified":"2026-03-19T17:44:09Z","published":"2026-03-19T17:25:42Z","url":"https://euvdservices.enisa.europa.eu/api/enisaid?id=EUVD-2026-13137","html_url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-13137","id":"EUVD-2026-13137","imported":"2026-07-17T22:27:57.193Z"}]},"references":[{"type":"WEB","url":"https://github.com/advisories/GHSA-24vq-qfc5-qrmj"},{"type":"WEB","url":"https://github.com/wolfSSL/wolfssl/pull/9748"},{"type":"WEB","url":"https://github.com/wolfSSL/wolfssl/pull/9949"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-2646"}],"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-2026-702.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:H/AT:P/PR:L/UI:N/VC:L/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/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"}]}
