Issue of the Implementation # L0149

Brief

rtl8187: fix use after free on failure path in rtl8187_probe()

Detailed Description

If allocation of io_dmabuf fails, rtl8187_probe() calls usb_put_dev(udev) while usb_get_dev(udev) is not called yet. As a result refcnt is decremented incorrectly and usb_dev can be used after memory deallocation.
