CVE-2013-6392 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-6392):
  The genlock_dev_ioctl function in genlock.c in the Genlock driver for the
  Linux kernel 3.x, as used in Qualcomm Innovation Center (QuIC) Android
  contributions for MSM devices and other products, does not properly
  initialize a certain data structure, which allows local users to obtain
  sensitive information from kernel stack memory via a crafted
  GENLOCK_IOC_EXPORT ioctl call.


Unclear if this one is fixed.

I found references to this only in the Kernel tree for Qualcomm chipsets.
Which we don't ship.
