Official description
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.
