Missing Bounds Check in Inner Loop of Escape Handler for 0x7000014
There is a missing bounds check in inner loop of the escape handler for 0x7000014 that leads to a stack buffer overflow. The attached PoC gives the following crashing context (Win 10 x64, 372.54): DRIVER_OVERRAN_STACK_BUFFER (f7). A driver has overrun a stack-based buffer. This overrun could potentially allow a malicious user to gain control of this machine.
Mitigation:
Ensure that bounds checks are performed on user-controlled data before it is used to access memory.
