Use it here too.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98664","source_modified_at":"2026-10-21T12:55:29.309Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"ae1d37a9bb4bd8d9091a40d153143e99b115ee37","lessThan":"d3078aaef8af4648f94eeafde4b7b36efd9838d1","status":"affected","versionType":"git"},{"version":"ae1d37a9bb4bd8d9091a40d153143e99b115ee37","lessThan":"e9b4c00f775a915b759b08bfe2c5e806a8301a59","status":"affected","versionType":"git"},{"version":"ae1d37a9bb4bd8d9091a40d153143e99b115ee37","lessThan":"50e8d70ba0743f88afd7e49f9cebd1841ee677f5","status":"affected","versionType":"git"},{"version":"ae1d37a9bb4bd8d9091a40d153143e99b115ee37","lessThan":"f501302ebb9e1504162351b951fe3ae331c852ab","status":"affected","versionType":"git"},{"version":"ae1d37a9bb4bd8d9091a40d153143e99b115ee37","lessThan":"d94787287a113a1326211647d5e0deed1e9de105","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98664","source_modified_at":"2026-10-21T12:55:29.309Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"5.8","status":"affected"},{"version":"0","lessThan":"5.8","status":"unaffected","versionType":"semver"},{"version":"6.6.160","lessThanOrEqual":"6.6.*","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":"7.2.10","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-2026-98664","source_modified_at":"2026-10-21T12:55:29.309Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"50e8d70ba0743f88afd7e49f9cebd1841ee677f5","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":0.002,"percentile":0.09315,"score_date":"2026-10-23"},"published_at":"2026-10-18T15:44:32.940Z","modified_at":"2026-10-21T12:55:29.309Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-98664","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-21T12:55:29.309Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-98664","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/d3078aaef8af4648f94eeafde4b7b36efd9838d1"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/e9b4c00f775a915b759b08bfe2c5e806a8301a59"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/50e8d70ba0743f88afd7e49f9cebd1841ee677f5"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/f501302ebb9e1504162351b951fe3ae331c852ab"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/d94787287a113a1326211647d5e0deed1e9de105"}],"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":"2026-10-21T12:55:29.309Z","content_hash":"f0cf2d1421ce10389389bbfd5f18819772712722a2b1da24f2b04ed639473246"}}
