Let's just do a NOFAIL allocation and the problem goes away.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98445","source_modified_at":"2026-10-19T09:19:40.826Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"be408417630427984a1fddd069f30b245793234c","lessThan":"3380151cf0ce8ad0c1d356fed51e4b69e1d28e50","status":"affected","versionType":"git"},{"version":"be408417630427984a1fddd069f30b245793234c","lessThan":"b15c79fca28060fd9c7e77f2c3ebc4ba023974e8","status":"affected","versionType":"git"},{"version":"be408417630427984a1fddd069f30b245793234c","lessThan":"0e0d3372a84029da1768c7a4c4601484af5b58a2","status":"affected","versionType":"git"},{"version":"be408417630427984a1fddd069f30b245793234c","lessThan":"ab1c416d2377cdc16123ef521aac4da1c468c3d4","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98445","source_modified_at":"2026-10-19T09:19:40.826Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"6.8","status":"affected"},{"version":"0","lessThan":"6.8","status":"unaffected","versionType":"semver"},{"version":"6.12.113","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.56","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.9","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-2026-98445","source_modified_at":"2026-10-19T09:19:40.826Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"3380151cf0ce8ad0c1d356fed51e4b69e1d28e50","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98445","source_modified_at":"2026-10-19T09:19:40.826Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"0e0d3372a84029da1768c7a4c4601484af5b58a2","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":0.00168,"percentile":0.05743,"score_date":"2026-10-23"},"published_at":"2026-10-18T15:14:55.754Z","modified_at":"2026-10-19T09:19:40.826Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-98445","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-19T09:19:40.826Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-98445","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/3380151cf0ce8ad0c1d356fed51e4b69e1d28e50"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/b15c79fca28060fd9c7e77f2c3ebc4ba023974e8"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/0e0d3372a84029da1768c7a4c4601484af5b58a2"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/ab1c416d2377cdc16123ef521aac4da1c468c3d4"}],"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":"2026-10-19T09:19:40.826Z","content_hash":"6e7a1e6874de9411118740c8af02be2b4586a8ef6c318bf8852176c33c66d435"}}
