{"id":"CVE-2026-98696","summary":"USB: serial: fix driver deregistration order","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nUSB: serial: fix driver deregistration order\n\nUSB serial driver modules register one driver for the USB bus and one or\nmore drivers for the ports on the USB serial bus.\n\nWhen unloading a driver module, the USB driver must be deregistered\nbefore the USB serial bus drivers so that I/O is stopped before\nunbinding the ports to avoid use-after-free in completion handlers\naccessing port data.\n\nNote that the \"new_id\" attributes must first be removed to prevent new\nids from being added and triggering a probe of the USB driver after it\nhas been deregistered.","modified":"2026-11-04T14:27:18.052790417Z","published":"2026-10-18T15:46:20.399Z","related":["SUSE-SU-2026:5091-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98696.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/2f12343f39e316ff66adc84a6db3569f33b50f66"},{"type":"WEB","url":"https://git.kernel.org/stable/c/428d479a0d31460fbf5969ab262ccd673f1fac01"},{"type":"WEB","url":"https://git.kernel.org/stable/c/646e5b28b4fdbc1b828a2398d6ced2c1dd308a46"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7c65438e3b98bd6009af09db8c725547192cdfe0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/991904982827f07706c643bb0428c4b689b254e3"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9b085a06a0a411b0bcdf18b61c3ebf1be1c72ffe"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a1aa474768f69ea3a70da523f00f74c264cfa10e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e7ad832b1144df19cbbaaa655625c6f984e85b9f"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98696.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98696"},{"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":"765e0ba62613fb90f09c1b5926750df0aa56f349"},{"fixed":"991904982827f07706c643bb0428c4b689b254e3"},{"fixed":"7c65438e3b98bd6009af09db8c725547192cdfe0"},{"fixed":"2f12343f39e316ff66adc84a6db3569f33b50f66"},{"fixed":"e7ad832b1144df19cbbaaa655625c6f984e85b9f"},{"fixed":"9b085a06a0a411b0bcdf18b61c3ebf1be1c72ffe"},{"fixed":"a1aa474768f69ea3a70da523f00f74c264cfa10e"},{"fixed":"428d479a0d31460fbf5969ab262ccd673f1fac01"},{"fixed":"646e5b28b4fdbc1b828a2398d6ced2c1dd308a46"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-98696.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.4.0"},{"fixed":"5.10.273"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.224"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.191"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.160"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.113"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.56"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.10"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-98696.json"}}],"schema_version":"1.9.2"}
