Name of the Vulnerable Software and Affected Versions IObit Smart Defrag version 6

Description The issue concerns the SmartDefragDriver.sys driver in IObit Smart Defrag 6, which fails to free an executable kernel pool allocated with user-defined bytes and size when a specific IOCTL (0x9C401CC4) is called.
