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.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98161","source_modified_at":"2026-10-21T12:54:44.996Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"c5d4355d10d414a96ca870b731756b89d068d57a","lessThan":"22d1f4dcdc9c6d0295c6db0c8933126098b14e05","status":"affected","versionType":"git"},{"version":"c5d4355d10d414a96ca870b731756b89d068d57a","lessThan":"d34c30bc994328d9cf6749b2e9a32aabd08fd076","status":"affected","versionType":"git"},{"version":"c5d4355d10d414a96ca870b731756b89d068d57a","lessThan":"770a90c2127220f0fc194ce909ad4f0842e141cb","status":"affected","versionType":"git"},{"version":"c5d4355d10d414a96ca870b731756b89d068d57a","lessThan":"72561ca1ab96f0f0f32737a6171641e05a318538","status":"affected","versionType":"git"},{"version":"c5d4355d10d414a96ca870b731756b89d068d57a","lessThan":"c644a2f8fef5618fcf453c591177700fd07dd024","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98161","source_modified_at":"2026-10-21T12:54:44.996Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"5.3","status":"affected"},{"version":"0","lessThan":"5.3","status":"unaffected","versionType":"semver"},{"version":"6.6.160","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.112","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.52","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.6","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}],"defaultStatus":"affected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98161","source_modified_at":"2026-10-21T12:54:44.996Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"22d1f4dcdc9c6d0295c6db0c8933126098b14e05","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98161","source_modified_at":"2026-10-21T12:54:44.996Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"770a90c2127220f0fc194ce909ad4f0842e141cb","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98161","source_modified_at":"2026-10-21T12:54:44.996Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"72561ca1ab96f0f0f32737a6171641e05a318538","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":0.00114,"percentile":0.01389,"score_date":"2026-10-23"},"published_at":"2026-09-25T13:06:51.138Z","modified_at":"2026-10-21T12:54:44.996Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-98161","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-21T12:54:44.996Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-98161","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://git.kernel.org/stable/c/22d1f4dcdc9c6d0295c6db0c8933126098b14e05"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/d34c30bc994328d9cf6749b2e9a32aabd08fd076"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/770a90c2127220f0fc194ce909ad4f0842e141cb"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/72561ca1ab96f0f0f32737a6171641e05a318538"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/c644a2f8fef5618fcf453c591177700fd07dd024"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-21T12:54:44.996Z","content_hash":"3787db80f8b7b50dd8cc575ba23deb3f17c6ca56bb4f641ba9c153e03db1dc36"}}
