      "title": "usb: gadget: f_rndis: Fix net_device lifecycle with device_move",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nusb: gadget: f_rndis: Fix net_device lifecycle with device_move\n\nThe net_device is allocated during function instance creation and\nregistered during the bind phase with the gadget device as its sysfs\nparent. When the function unbinds, the parent device is destroyed, but\nthe net_device survives, resulting in dangling sysfs symlinks:\n\n  console:/ # ls -l /sys/class/net/usb0\n  lrwxrwxrwx ... /sys/class/net/usb0 ->\n  /sys/devices/platform/.../gadget.0/net/usb0\n  console:/ # ls -l /sys/devices/platform/.../gadget.0/net/usb0\n  ls: .../gadget.0/net/usb0: No such file or directory\n\nUse device_move() to reparent the net_device between the gadget device\ntree and /sys/devices/virtual across bind and unbind cycles. During the\nfinal unbind, calling device_move(NULL) moves the net_device to the\nvirtual device tree before the gadget device is destroyed. On rebinding,\ndevice_move() reparents the device back under the new gadget, ensuring\nproper sysfs topology and power management ordering.\n\nTo maintain compatibility with legacy composite drivers (e.g., multi.c),\nthe borrowed_net flag is used to indicate whether the network device is\nshared and pre-registered during the legacy driver's bind phase.",
