Fix by storing allocated buffers into bp->queues[0] ASAP.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98492","source_modified_at":"2026-10-19T09:20:29.361Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"78d901897b3cae06b38f54e48a2378cf9da21175","lessThan":"bda487567d0b7b15dfa876511085c0666b9efad5","status":"affected","versionType":"git"},{"version":"78d901897b3cae06b38f54e48a2378cf9da21175","lessThan":"259e6cbb6a097da8ced544ee92a6fbde35aa1338","status":"affected","versionType":"git"},{"version":"78d901897b3cae06b38f54e48a2378cf9da21175","lessThan":"23d42b9a3bcd55b17d3b371544fedc708c2397e9","status":"affected","versionType":"git"},{"version":"982a4d9a2e12b693f684eff943043a607628d871","status":"affected","versionType":"git"},{"version":"6.17.3","lessThan":"6.18","status":"affected","versionType":"semver"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98492","source_modified_at":"2026-10-19T09:20:29.361Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"6.18","status":"affected"},{"version":"0","lessThan":"6.18","status":"unaffected","versionType":"semver"},{"version":"6.18.55","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-2026-98492","source_modified_at":"2026-10-19T09:20:29.361Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"259e6cbb6a097da8ced544ee92a6fbde35aa1338","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98492","source_modified_at":"2026-10-19T09:20:29.361Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"23d42b9a3bcd55b17d3b371544fedc708c2397e9","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98492","source_modified_at":"2026-10-19T09:20:29.361Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"6.18","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":0.00198,"percentile":0.09054,"score_date":"2026-10-23"},"published_at":"2026-10-18T15:16:21.208Z","modified_at":"2026-10-19T09:20:29.361Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-98492","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-19T09:20:29.361Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-98492","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/bda487567d0b7b15dfa876511085c0666b9efad5"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/259e6cbb6a097da8ced544ee92a6fbde35aa1338"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/23d42b9a3bcd55b17d3b371544fedc708c2397e9"}],"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":"2026-10-19T09:20:29.361Z","content_hash":"e8b68a7c7e4dc9d0541755c06ad2450e4689e6073a86117739a694c2673f53ee"}}
