CVE-2024-36896 is a race-condition flaw in the Linux kernel USB core's port-device sysfs handling. In the disable_store() and disable_show() routines, usb_hub_to_struct_hub() can return NULL when the hub associated with a USB port is removed concurrently. The routines dereference the returned hub structure without first validating it, causing an access violation. The fix removes an unnecessary early dereference by using the port device parent where appropriate and adds NULL checks before further hub access.
