  "title": "usb: gadget: f_ncm: Refactor bind path to use __free()",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  usb: gadget: f_ncm: Refactor bind path to use __free()  After an bind/unbind cycle, the ncm-\u003Enotify_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-\u003Eops-\u003Efree_request.  Refactor the error handling in the bind path to use the __free() automatic cleanup mechanism.  Unable to handle kernel NULL pointer dereference at virtual address 0000000000000020 Call trace:  usb_ep_free_request\u002B0x2c/0xec  ncm_bind\u002B0x39c/0x3dc  usb_add_function\u002B0xcc/0x1f0  configfs_composite_bind\u002B0x468/0x588  gadget_bind_driver\u002B0x104/0x270  really_probe\u002B0x190/0x374  __driver_probe_device\u002B0xa0/0x12c  driver_probe_device\u002B0x3c/0x218  __device_attach_driver\u002B0x14c/0x188  bus_for_each_drv\u002B0x10c/0x168  __device_attach\u002B0xfc/0x198  device_initial_probe\u002B0x14/0x24  bus_probe_device\u002B0x94/0x11c  device_add\u002B0x268/0x48c  usb_add_gadget\u002B0x198/0x28c  dwc3_gadget_init\u002B0x700/0x858  __dwc3_set_mode\u002B0x3cc/0x664  process_scheduled_works\u002B0x1d8/0x488  worker_thread\u002B0x244/0x334  kthread\u002B0x114/0x1bc  ret_from_fork\u002B0x10/0x20",
