{"id":"CVE-2026-98896","summary":"thunderbolt: Keep the domain reference while processing hotplug","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nthunderbolt: Keep the domain reference while processing hotplug\n\nWe process hotplug events in a workqueue that may run after the domain\nhas been removed by tb_domain_remove(). For example if user unloads the\ndriver while at the same time plugging  a device router we may have\nscheduled tb_handle_hotplug() to run. Avoid possible UAF in this case by\ntaking the domain reference before scheduling the hotplug handler in\ntb_queue_hotplug().","modified":"2026-11-04T14:27:17.226825901Z","published":"2026-10-23T11:37:58.225Z","related":["SUSE-SU-2026:5091-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98896.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/04df2985159e381c88a923fae1bec2f8d0272412"},{"type":"WEB","url":"https://git.kernel.org/stable/c/06b2e894e640f6a3dbeb536a2d26d72426b26a46"},{"type":"WEB","url":"https://git.kernel.org/stable/c/0a87af3b1e3aa2e09d160848daf0c39e765b73de"},{"type":"WEB","url":"https://git.kernel.org/stable/c/138ec65b2c761f065b19d115aed2b8246fc272f5"},{"type":"WEB","url":"https://git.kernel.org/stable/c/1d991f749a8255ee2ecc6307e2f27354ab631827"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b61a4ae2ec6a0d363615d01106e0a2d284133a38"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e8656465d08ed832e120c9cca4a6d0c8ccb45698"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98896.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98896"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"d6cc51cd1a4aed1d9e2dd66d643d729acb4be560"},{"fixed":"06b2e894e640f6a3dbeb536a2d26d72426b26a46"},{"fixed":"1d991f749a8255ee2ecc6307e2f27354ab631827"},{"fixed":"e8656465d08ed832e120c9cca4a6d0c8ccb45698"},{"fixed":"b61a4ae2ec6a0d363615d01106e0a2d284133a38"},{"fixed":"04df2985159e381c88a923fae1bec2f8d0272412"},{"fixed":"0a87af3b1e3aa2e09d160848daf0c39e765b73de"},{"fixed":"138ec65b2c761f065b19d115aed2b8246fc272f5"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-98896.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.17.0"},{"fixed":"5.10.271"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.222"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.189"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.158"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.111"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.53"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-98896.json"}}],"schema_version":"1.9.2"}
