Description
In the Linux kernel, the following vulnerability has been resolved:
can: peak_usb: fix use after free bugs
After calling peak_usb_netif_rx_ni(skb), dereferencing skb is unsafe.
Especially, the can_frame cf which aliases skb memory is accessed
after the peak_usb_netif_rx_ni().
Reordering the lines solves the issue.
