The\nPTE-level change_softleaf_pte() does this correctly; mirror that here,\nmatching what copy_huge_pmd() does for the fork path.  Without the carry,\na plain mprotect() over a UFFD_WP-marked device-private THP strips the bit\nand the trap is bypassed on swap-in.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/2611f7521c6c124b1bef1be4fc319e0ca144502f","https://git.kernel.org/stable/c/f7e2c21bd1f57cd5350eecdfdb5d6025ca6afbab"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:48:17.459049833+00:00"},"epss":{"cve":"CVE-2026-72180","score":0.0021,"percentile":0.11204,"date":"2026-10-31"},"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).
