This\nprovides deterministic buffer contents, which is useful when the buffer\nis used directly as a map key.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/1f0f61573ba4cb899105b5cef65be3ca02205f93","https://git.kernel.org/stable/c/4acc761b4e3feca1eb648d21fc4d665b23c5372d","https://git.kernel.org/stable/c/6f5a7bcc049709af12e403111d5e73e80910dafc","https://git.kernel.org/stable/c/f523359c4789bb0396d2d642464a6e2fd4f2299d","https://git.kernel.org/stable/c/f5d242825ca417bb6afe35fde6e8880f97ca43fb"],"products":[],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2026-90300","score":0.00209,"percentile":0.1093,"date":"2026-10-25"},"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).
