In the Linux kernel, the following vulnerability has been resolved:
netfilter: nfnetlink_log: account for netlink header size
This is a followup to an old bug fix: NLMSG_DONE needs to account
for the netlink header size, not just the attribute size.
This can result in a WARN splat + drop of the netlink message,
but other than this there are no ill effects.
