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.
