UBUNTU-CVE-2024-44999: Medium severity ubuntu/linux-azure vulnerability
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 pskbinetmaypull() to fix this issue.

In the Linux kernel GTP driver, update gtp_dev_xmit() to use pskb_inet_may_pull() so the IPv4 or IPv6 network header is pulled into skb->head before accessing its fields.
