Details

In the Linux kernel, the following vulnerability has been resolved:

gtp: pull network headers in gtpdevxmit()

syzbot/KMSAN reported use of uninit-value in getdevxmit() [1]

We must make sure the IPv4 or Ipv6 header is pulled in skb->head before accessing fields in them.

Use pskbinetmay_pull() to fix this issue.
