For cross-directory renames where the target parent\nis a descendant of the source parent, lock the target parent before the\nsource parent so the directory order matches the child-to-parent order used\nby ntfs_file_fsync(), ntfs_dir_fsync(), and __ntfs_write_inode().","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/b3d09502b80dfe0bab9090ca532710da389f6c7f","https://git.kernel.org/stable/c/eb94f5a41a193a425e09a63cb75dffd151d8f42e"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:48:17.459049833+00:00"},"epss":{"cve":"CVE-2026-72190","score":0.00198,"percentile":0.0957,"date":"2026-11-01"},"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).
