Description

A flaw was found in the Linux kernel's usb: gadget: f_ecm component. When a USB gadget function unbinds, the associated net_device may not be properly de-parented from the destroyed gadget device. This can lead to dangling symbolic links in the /sys/class/net/ directory, potentially causing issues with system resource management and integrity.
