Handling errors in UAS and the storage driver may\ninvolve resetting a device. The thread doing the reset itself\nrelies on VM magic. However, that is insufficient, as resetting\na device involves resuming it. Resumption as well as resetting\ninvolves conrol transfers to the parent of the device to be reset.\nThat may be a root hub. Hence usbcore must heed the flags passed\nto usb_submit_urb() processing control transfers to root hubs.\n\nThe problem exist since the storage driver has been merged.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Vendor advisories\n\n- **Red Hat VEX** · Low · affected: Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 6, Red Hat Enterprise Linux 7, Red Hat Enterprise Linux 8, Red Hat Enterprise Linux 9, Red Hat OpenShift Container Platform 4 · no fix planned: Red Hat Enterprise Linux 6, Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 7, Red Hat Enterprise Linux 8, … · updated 2026-10-17 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-97483.json)","depth":"sunlit","depthScore":30,"depthScoreParts":{"impact":30.3,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[{"seq":213455,"id":"CVE-2026-97483","ts":1790754732011,"field":"cvss","old":null,"new":"5.5"},{"seq":213454,"id":"CVE-2026-97483","ts":1790754732011,"field":"severity","old":"none","new":"medium"}]}
