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

Public security bug reported:

The kgsl graphics 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 prevent write access to IOMMU context
registers, which allows local users to select a custom page table, and
consequently write to arbitrary memory locations, by using a crafted GPU
command stream to modify the contents of a certain register.
