Security update for Linux Kernel Live Patch 4 (important)

This kernel live patch for Linux Kernel 3.12.39-47.1 fixes two security
issues:

• CVE-2015-7613: A race condition in the IPC object implementation in the
  Linux kernel allowed local users to gain privileges by triggering an
  ipc_addid call that leads to uid and gid comparisons against
  uninitialized data, related to msg.c, shm.c, and util.c. (bsc#948701
  bsc#948536)
• CVE-2015-5707: Integer overflow in the sg_start_req function in
  drivers/scsi/sg.c in the Linux kernel allowed local users to cause a
  denial of service or possibly have unspecified other impact via a large
  iov_count value in a write request. (bsc#940342 bsc#940338)
