  "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.",
