Description
Description
In the Linux kernel, the following vulnerability has been resolved:
usb: gadget: fix null pointer dereference in usb_put_function_instance()
usb_put_function_instance() attempts to dereference fd inside fi struct
to get mod in uvc_alloc_inst() error path. However, fd is not allocated
until later in try_get_usb_function_instance() after allocating fi in
uvc_alloc_inst() and thus guranteed to be null in error path. Fix this
by adding a null check for fi->fd that returns if fd is null.
