Let's just do a NOFAIL allocation and the problem goes away.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/0e0d3372a84029da1768c7a4c4601484af5b58a2","https://git.kernel.org/stable/c/3380151cf0ce8ad0c1d356fed51e4b69e1d28e50","https://git.kernel.org/stable/c/ab1c416d2377cdc16123ef521aac4da1c468c3d4","https://git.kernel.org/stable/c/b15c79fca28060fd9c7e77f2c3ebc4ba023974e8"],"products":[],"source":"nvd","synced_at":"2026-10-19T23:00:53.604569364+00:00"},"epss":{"cve":"CVE-2026-98445","score":0.00168,"percentile":0.06026,"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).
