A random memory access flaw was found in the Linux kernel's GPU i915 kernel
driver functionality in the way a user may run malicious code on the GPU.
This flaw allows a local user to crash the system or escalate their
privileges on the system.

Sushma Venkatesh Reddy discovered that the Intel i915 graphics driver in
the Linux kernel did not perform a GPU TLB flush in some situations. A
local attacker could use this to cause a denial of service or possibly
execute arbitrary code.
