**Description**
A security feature bypass issue exists due to the Windows kernel's failure to properly initialize a memory address. This allows an attacker to retrieve information that could lead to a Kernel Address Space Layout Randomization (KASLR) bypass. An attacker who successfully exploits this issue could retrieve the base address of the kernel driver from a compromised process. To exploit this issue, an attacker would have to log on to an affected system and run a specially crafted application.
