{"id":"CVE-2026-98018","summary":"net: mctp: i3c: serialize probe with bus removal","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet: mctp: i3c: serialize probe with bus removal\n\nmctp_i3c_probe() drops busdevs_lock after finding the matching bus. 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().","modified":"2026-09-26T03:48:31.295635410Z","published":"2026-09-25T10:23:39.706Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98018.json"},"references":[{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2b4707a149a55e8fa75c9ef32b359d60f470a566"},{"type":"WEB","url":"https://git.kernel.org/stable/c/765c5e357e67916a7aac8ead4ac2fa7d2bffe000"},{"type":"WEB","url":"https://git.kernel.org/stable/c/906d8dbafabfa81a30e3ade420cb9912f223a5e1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e6541b2747682fdb2c6ded4a7cf7c39c4067a35c"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98018.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98018"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"c8755b29b58ec65be17bcb8c40763d2dcb1f1db5"},{"fixed":"e6541b2747682fdb2c6ded4a7cf7c39c4067a35c"},{"fixed":"765c5e357e67916a7aac8ead4ac2fa7d2bffe000"},{"fixed":"906d8dbafabfa81a30e3ade420cb9912f223a5e1"},{"fixed":"2b4707a149a55e8fa75c9ef32b359d60f470a566"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98018.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.111"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.53"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.7"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98018.json"}}],"schema_version":"1.9.0"}
