The DxgkDdiEscape handler for 0x7000170 lacks proper bounds checks for the variable size
|
|
input escape data, and relies on a user provided size as the upper bound for writing output.

Crashing context with PoC (Win 10 x64 with 372.54):

KERNEL_SECURITY_CHECK_FAILURE (139)
|
|
A kernel component has corrupted a critical data structure. The corruption
|
|
could potentially allow a malicious user to gain control of this machine.

To reproduce, compile the PoC as a x64 binary (requires linking with
|
|
setupapi.lib, and WDK for D3DKMTEscape), and run. It may require some changes
|
|
as for it to work as the escape data must contain the right values (e.g. a
|
|
field that appears to be gpu bus device function). My PoC should hopefully set
|
|
all the right values for the machine it's running on.
