SmartDefragDriver.sys (2.0) in IObit Smart Defrag 6 never frees an executable kernel pool that is allocated with user defined bytes and size when IOCTL 0x9C401CC4 is called. This kernel pointer can be leaked if the kernel pool becomes a "big" pool.
The product does not sufficiently track and release allocated memory after it has been used, making the memory unavailable for reallocation and reuse.
