- Summary
- arp: do not assume dev_hard_header() does not change skb->head
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
arp: do not assume devhardheader() does not change skb->head
arpcreate() is the only devhard_header() caller making assumption about skb->head being unchanged.
A recent commit broke this assumption.
Initialize @arp pointer after devhardheader() call.
