It also uses a kernel\npage-table accessor on user page tables and supports only PMD-level large\nmappings on x86-64.\n\nRemove the direct walker. Send interrupt faults directly to user polling\nmode so the existing call-OS fallback retries them in process context.\n\nRemove the mmap-lock failure statistic that can no longer be incremented.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":[],"references":["https://git.kernel.org/stable/c/5a540ced720b4397306337cab34af1af4b30827c","https://git.kernel.org/stable/c/6248eb1833ff0adfdbbadd5f846c2f22e02a01b0","https://git.kernel.org/stable/c/877423f595b60f8fe7c18b64a5d283d9e1732a13","https://git.kernel.org/stable/c/928a8e9f523df845fc496bcb9811013b67aabec5","https://git.kernel.org/stable/c/ef81e4a1628ecfb9cfc442de10883f383faf17a1"],"products":[],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2026-90383","score":0.00164,"percentile":0.05546,"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).
