The VBIOS image is copied out with kmemdup() before\nthe table is released, so it remains valid for the caller.\n\n(cherry picked from commit ca5988682b4cba4cd125a0fa99b2de1239164ae4)","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/1748043b5114ce5ee5ee874d5f821a158d70631c","https://git.kernel.org/stable/c/312278b3091912fa56a6a587609f17dcb33465c2","https://git.kernel.org/stable/c/50a75929c0c5e8ab29a3ac49dc92489873d9d261","https://git.kernel.org/stable/c/65bff26617607c1331283232016c0e89088c5b78","https://git.kernel.org/stable/c/9b7de3ee5d2c5ee2a706e5f7ca0126f4fbea4da8"],"products":[],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2026-68238","score":0.00168,"percentile":0.0604,"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).
