{"id":"CVE-2026-90031","summary":"usb-storage: ene_ub6250: fix race between scan work and probe","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nusb-storage: ene_ub6250: fix race between scan work and probe\n\nene_ub6250_probe() calls usb_stor_probe2(), which starts the usb-storage\ninfrastructure and schedules the delayed scan work.  The driver then\ncalls ene_get_card_type(), which sends an ENE command through\nene_send_scsi_cmd() and the usb-storage bulk transfer helpers.\n\nBoth the delayed scan work, through usb_stor_Bulk_max_lun(), and\nene_get_card_type() use us-\u003ecurrent_urb.  The scan work serializes this\naccess with us-\u003edev_mutex, but the ENE card-type probe does not.  If the\nscan work runs while ene_get_card_type() is still using us-\u003ecurrent_urb,\nusb_submit_urb() warns that the URB is already active.\n\nSerialize ene_get_card_type() with us-\u003edev_mutex, matching the locking\nused by the scan path.","modified":"2026-09-25T18:27:06.930808219Z","published":"2026-09-16T10:33:32.524Z","related":["openSUSE-SU-2026:11880-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90031.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/1c67f2ba9c5f7c5ab3670671c0d51c6504bcaf74"},{"type":"WEB","url":"https://git.kernel.org/stable/c/445fc368c6bc73eff0aeb3818cf5f355facfbb16"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5082546702c32a2700894d2c0ace784e038ef6a3"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8936d95dd04d34db96d4d1e3899eee52605bbedc"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9481bc04a8c351ed883a7f0e10939bbe9120ead7"},{"type":"WEB","url":"https://git.kernel.org/stable/c/996c319b8bd5ada1f62daae0d331d0b23e0f2117"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9c261a83131e241d67cb73ab578d0265bc19cfb5"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9cd335f4f41e84d1ab88d80150ffee8dee9650d7"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90031.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90031"},{"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":"41e568d14ec0aca1b2bb19563517aad3b06d6805"},{"fixed":"9cd335f4f41e84d1ab88d80150ffee8dee9650d7"},{"fixed":"8936d95dd04d34db96d4d1e3899eee52605bbedc"},{"fixed":"9c261a83131e241d67cb73ab578d0265bc19cfb5"},{"fixed":"9481bc04a8c351ed883a7f0e10939bbe9120ead7"},{"fixed":"5082546702c32a2700894d2c0ace784e038ef6a3"},{"fixed":"1c67f2ba9c5f7c5ab3670671c0d51c6504bcaf74"},{"fixed":"996c319b8bd5ada1f62daae0d331d0b23e0f2117"},{"fixed":"445fc368c6bc73eff0aeb3818cf5f355facfbb16"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-90031.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.6.39"},{"fixed":"5.10.270"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.221"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"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":"6.18.51"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-90031.json"}}],"schema_version":"1.9.0"}
