These were fixed in the respective patched releases.","published":"2026-08-19T14:17:52.797","modified":"2026-08-19T14:17:52.797","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://github.com/celabshq/libcrux/security/advisories/GHSA-435g-fcv3-8j26"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/libcrux-before-cryptographic-implementation-bug-fixes"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-19T14:17:52.797"}}
