CVE-2013-3227 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-3227):
  The caif_seqpkt_recvmsg function in net/caif/caif_socket.c in the Linux
  kernel before 3.9-rc7 does not initialize a certain length variable, which
  allows local users to obtain sensitive information from kernel stack memory
  via a crafted recvmsg or recvfrom system call.
