Several failure\npaths in raid10_write_request() complete the bio and return without\nreaching the normal write completion path, causing the corresponding\nmd_write_end() to be skipped.\n\nMake raid10_write_request() return a status indicating whether the write\nrequest was successfully queued. This allows raid10_make_request() to\nrelease the writes_pending reference with md_write_end() when a write\nrequest fails.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/b6667d925c274910423385042edf18f6788dbceb","https://git.kernel.org/stable/c/c642583adc136d4c70ce3c65c3f43e847d26c776","https://git.kernel.org/stable/c/e045d6ed33f8faa3e3dd6dc33c62ec01e3ad275d","https://git.kernel.org/stable/c/f076460c5205c9687059e5a3afeed37d2f2ceb6b","https://git.kernel.org/stable/c/f94031c94eaebe14a7c9e91720064de0c5a54a6c"],"products":[],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2026-72439","score":0.00175,"percentile":0.06996,"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).
