A flaw was found in the Linux kernel's usb: gadget: f_subset component. This vulnerability arises from an issue in how network device resources are managed during the unbinding of a USB gadget function. When the parent device is destroyed, the associated network device may persist, creating non-functional links in the system's file structure. This improper resource handling can lead to system instability or unexpected behavior.
