*** This bug is a security vulnerability ***

Public security bug reported:

The mdp_lut_hw_update function in drivers/video/msm/mdp.c in the MDP
display driver for the Linux kernel 3.x, as used in Qualcomm Innovation
Center (QuIC) Android contributions for MSM devices and other products,
does not validate certain start and length values within an ioctl call,
which allows attackers to gain privileges via a crafted application.
