Otherwise, the folio will not be freed, causing memory\nleak.\n\nThis leak would happen on a filesystem with blocksize > page_size and a\ntruncate is performed, where the blocksize makes folios split to >0 order\nones, causing truncated folios not being freed.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":["CWE-401"],"references":["https://git.kernel.org/stable/c/14efb4793519d73fb2902bb0ece319b886e4b4b9","https://git.kernel.org/stable/c/86368616a9ce51f6b41efa251b6e066893851d67","https://git.kernel.org/stable/c/92ad820a1f2d95d5a8d6c2bd3f391bbb068a5f9e"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:00:57.946988208+00:00"},"epss":{"cve":"CVE-2025-22000","score":0.00189,"percentile":0.08612,"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).
