"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nusb: gadget: composite: fix dead empty check in the USB_DT_OTG handler\n\nThe OTG branch of composite_setup() falls back to the first\nconfiguration when none is selected:\n\n\tif (cdev->config)\n\t\tconfig = cdev->config;\n\telse\n\t\tconfig = list_first_entry(&cdev->configs,\n\t\t\t\t\t struct usb_configuration, list);\n\tif (!config)\n\t\tgoto done;\n\t...\n\tmemcpy(req->buf, config->descriptors[0], value);\n\nlist_first_entry() never returns NULL. On an empty list it returns\ncontainer_of() of the list head. So the \"if (!config)\" check is dead.\n\nWhen cdev->configs is empty, config points at the head inside struct\nusb_composite_dev. config->descriptors[0] reads whatever sits at that\noffset. The memcpy copies up to w_length bytes of it into the response\nbuffer.\n\ncdev->configs can be empty in two cases. One is a teardown race on\ngadget unbind with a control transfer in flight. The other is a driver\nthat sets is_otg before it adds a config. A reproducer that holds\ncdev->configs empty triggers a KASAN fault in this branch.\n\nUse list_first_entry_or_null() so the existing check does its job."
