This does not restore the write permission, which\nmay cause subsequent write operations on the same file to fail.\n\nFix this by calling exe_file_allow_write_access() before filp_close() to\nrestore the write permission properly.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/480ac88431703f2adbb8e6b5bd73c3f3cf9f3d7f","https://git.kernel.org/stable/c/54274ff90488b6c0f595a6518faed3cf0bc966eb","https://git.kernel.org/stable/c/6cce7bc7fac8471c832696720d9c8f2a976d9c54","https://git.kernel.org/stable/c/90f601b497d76f40fa66795c3ecf625b6aced9fd","https://git.kernel.org/stable/c/e785f552ab04dbca01d31f0334f4561240b04459"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:17:07.138532058+00:00"},"epss":{"cve":"CVE-2025-68239","score":0.00197,"percentile":0.09282,"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).
