Description

In the Linux kernel, the following vulnerability has been resolved: HID: nvidia-shield: Reference hid_device devm allocation of input_dev name Use hid_device for devm allocation of the input_dev name to avoid a use-after-free. input_unregister_device would trigger devres cleanup of all resources associated with the input_dev, free-ing the name. The name would subsequently be used in a uevent fired at the end of unregistering the input_dev.
