Keep asynchronous flush\nchaining for REQ_FUA. At that point, data copy has completed and the parent\nbio can wait for the chained flush bio.","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-754"],"references":["https://git.kernel.org/stable/c/22d1f4dcdc9c6d0295c6db0c8933126098b14e05","https://git.kernel.org/stable/c/72561ca1ab96f0f0f32737a6171641e05a318538","https://git.kernel.org/stable/c/770a90c2127220f0fc194ce909ad4f0842e141cb","https://git.kernel.org/stable/c/c644a2f8fef5618fcf453c591177700fd07dd024","https://git.kernel.org/stable/c/d34c30bc994328d9cf6749b2e9a32aabd08fd076"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2026-98161","score":0.00114,"percentile":0.0145,"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).
