A\nconcurrent I3C_NOTIFY_BUS_REMOVE can then unregister and free the bus\nnetdev before probe passes its private data to mctp_i3c_add_device().\nThe latter consequently adds a list node through a freed mbus pointer.\n\nKeep busdevs_lock held until the device has been added. This also\nsatisfies the __must_hold annotation on mctp_i3c_add_device().","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98018","source_modified_at":"2026-10-19T09:12:23.555Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"c8755b29b58ec65be17bcb8c40763d2dcb1f1db5","lessThan":"e6541b2747682fdb2c6ded4a7cf7c39c4067a35c","status":"affected","versionType":"git"},{"version":"c8755b29b58ec65be17bcb8c40763d2dcb1f1db5","lessThan":"765c5e357e67916a7aac8ead4ac2fa7d2bffe000","status":"affected","versionType":"git"},{"version":"c8755b29b58ec65be17bcb8c40763d2dcb1f1db5","lessThan":"906d8dbafabfa81a30e3ade420cb9912f223a5e1","status":"affected","versionType":"git"},{"version":"c8755b29b58ec65be17bcb8c40763d2dcb1f1db5","lessThan":"2b4707a149a55e8fa75c9ef32b359d60f470a566","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98018","source_modified_at":"2026-10-19T09:12:23.555Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"6.7","status":"affected"},{"version":"0","lessThan":"6.7","status":"unaffected","versionType":"semver"},{"version":"6.12.111","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.53","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.7","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-2026-98018","source_modified_at":"2026-10-19T09:12:23.555Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"765c5e357e67916a7aac8ead4ac2fa7d2bffe000","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98018","source_modified_at":"2026-10-19T09:12:23.555Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"906d8dbafabfa81a30e3ade420cb9912f223a5e1","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98018","source_modified_at":"2026-10-19T09:12:23.555Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"2b4707a149a55e8fa75c9ef32b359d60f470a566","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":0.00168,"percentile":0.05758,"score_date":"2026-10-23"},"published_at":"2026-09-25T10:23:39.706Z","modified_at":"2026-10-19T09:12:23.555Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-98018","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-19T09:12:23.555Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-98018","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/e6541b2747682fdb2c6ded4a7cf7c39c4067a35c"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/765c5e357e67916a7aac8ead4ac2fa7d2bffe000"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/906d8dbafabfa81a30e3ade420cb9912f223a5e1"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/2b4707a149a55e8fa75c9ef32b359d60f470a566"}],"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":"2026-10-19T09:12:23.555Z","content_hash":"26f015555d37c6c66129ee3eefe9d36d2dbd7d2bcf3fc24023df99f776c052a4"}}
