Description
In the Linux kernel, the following vulnerability has been resolved:
usb: cdns3: change place of 'priv_ep' assignment in cdns3_gadget_ep_dequeue(), cdns3_gadget_ep_enable()
If 'ep' is NULL, result of ep_to_cdns3_ep(ep) is invalid pointer
and its dereference with priv_ep->cdns3_dev may cause panic.
Found by Linux Verification Center (linuxtesting.org) with SVACE.
