Merge tag 'xsa448-6.8-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip

Pull xen netback fix from Juergen Gross:
 "Transmit requests in Xen's virtual network protocol can consist of
  multiple parts. While not really useful, except for the initial part
  any of them may be of zero length, i.e. carry no data at all.

  Besides a certain initial portion of the to be transferred data, these
  parts are directly translated into what Linux calls SKB fragments.
  Such converted request parts can, when for a particular SKB they are
  all of length zero, lead to a de-reference of NULL in core networking
  code"
