This\nis not done when using fixed scratch sizes via command line. This can\nresult in user specifying a size which is not aligned, and thus kernel\nreleasing a pageblock that is only partially scratch.\n\nDo the rounding up for both cases in scratch_size_update().","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/0e39380a7316122e1b00012b3f3cd3e318b3e7d3","https://git.kernel.org/stable/c/9fefab759f59bf891bef7be15aee4bc7caec7ec3","https://git.kernel.org/stable/c/b8271be34bce151597da5b5179e0648c281322a4"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:48:17.459049833+00:00"},"epss":{"cve":"CVE-2026-72169","score":0.00206,"percentile":0.10722,"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).
