Description:
 Race condition in the sclp_ctl_ioctl_sccb function in
 drivers/s390/char/sclp_ctl.c in the Linux kernel before 4.6 allows local
 users to obtain sensitive information from kernel memory by changing a
 certain length value, aka a "double fetch" vulnerability.
Ubuntu-Description:
 Pengfei Wang discovered a race condition in the s390 SCLP console driver
 for the Linux kernel when handling ioctl()s. A local attacker could use
 this to obtain sensitive information from kernel memory.
Notes:
 jdstrand> android kernels (flo, goldfish, grouper, maguro, mako and manta) are
  not supported on the Ubuntu Touch 14.10 and earlier preview kernels
 jdstrand> linux-lts-saucy no longer receives official support
 jdstrand> linux-lts-quantal no longer receives official support
 sbeattie> s390 only
