Smart Defrag Security Vulnerabilities

CVE-2019-6492

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.
