In the Linux kernel, the following vulnerability has been resolved:
usb: gadget: f_rndis: Refactor bind path to use __free()
After an bind/unbind cycle, the rndis->notify_req is left stale. If a
subsequent bind fails, the unified error label attempts to free this
stale request, leading to a NULL pointer dereference when accessing
ep->ops->free_request.
Refactor the error handling in the bind path to use the __free()
automatic cleanup mechanism.
