Title:
  Vhost-net made unstable by linux_3.8.0-28.41

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  On multiple machines with vm's using vhost-net this bug takes out the
  guest network interface under load.  The vm is only able to see
  broadcast traffic after this happens.  Started happening immediately
  after upgrading from linux-image-3.8.0-27-generic to linux-
  image-3.8.0-29-generic.  This changelog entry from linux_3.8.0-28.41
  seems particularly relevant:

    * vhost-net: fix use-after-free in vhost_net_flush
      - LP: #1202992
      - CVE-2013-4127

  Also seems to be giving the fedora folks fits as well:
