In the Linux kernel, the following vulnerability has been resolved:
can: pch_can: pch_can_rx_normal: fix use after free
After calling netif_receive_skb(skb), dereferencing skb is unsafe. Especially, the can_frame cf which aliases skb memory is dereferenced just after the call netif_receive_skb(skb).
Reordering the lines solves the issue.
