The HP Smart Array controller disk-array driver and Compaq SMART2
controller disk-array driver in the Linux kernel through 3.9.4 do not
initialize certain data structures, which allows local users to obtain
sensitive information from kernel memory via (1) a crafted
IDAGETPCIINFO command for a /dev/ida device, related to the
ida_locked_ioctl function in drivers/block/cpqarray.c or (2) a crafted
CCISS_PASSTHRU32 command for a /dev/cciss device, related to the
cciss_ioctl32_passthru function in drivers/block/cciss.c.
