{"id":"CVE-2026-93117","summary":"usb: fix UAF when probe runs concurrent to dyn ID removal","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nusb: fix UAF when probe runs concurrent to dyn ID removal\n\nDynamic IDs are only guaranteed to be valid when usb_dynids_lock is held,\nas remove_id_store can free the node. Thus, make a copy in\nusb_probe_interface. Clarify the documentation that the id parameter is\nonly valid during the probe.\n\nUSB serial has the same pattern, but it does not need fixing as the IDs\ncannot be removed via sysfs.","modified":"2026-09-19T03:47:31.530122193Z","published":"2026-09-17T16:11:24.509Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/93xxx/CVE-2026-93117.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/44904468e58d3dc3a0229782acbeb9677b060541"},{"type":"WEB","url":"https://git.kernel.org/stable/c/64320c6e721bdec4c43a789c866c8a099dd0c843"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7e795801295c84a6bbc10a3e7a4c99c50bfe45ac"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9b82ddf76827e2a8ff033a8131ecf24f2d6cae26"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e6a9c6b79b70046afdf5a1dbd03b1104536f30c0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ef8154d8b52d60338c1fd8d793cd8e891c604c14"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/93xxx/CVE-2026-93117.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-93117"},{"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":"0c7a2b72746a96f999fd2728520d03d94879be69"},{"fixed":"9b82ddf76827e2a8ff033a8131ecf24f2d6cae26"},{"fixed":"44904468e58d3dc3a0229782acbeb9677b060541"},{"fixed":"64320c6e721bdec4c43a789c866c8a099dd0c843"},{"fixed":"7e795801295c84a6bbc10a3e7a4c99c50bfe45ac"},{"fixed":"e6a9c6b79b70046afdf5a1dbd03b1104536f30c0"},{"fixed":"ef8154d8b52d60338c1fd8d793cd8e891c604c14"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-93117.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.6.33"},{"fixed":"6.1.188"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.157"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.110"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.52"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-93117.json"}}],"schema_version":"1.9.0"}
