Kernel Streaming Wow Thunk Service Driver
The issue is related to a buffer overflow in the dynamic memory of the Kernel Streaming WOW Thunk Service Driver, which can be exploited to elevate privileges. This can be achieved by manipulating the buffer size, followed by a copy operation, allowing an attacker to gain SYSTEM-level privileges. The vulnerability is caused by an integer overflow in the ksthunk.sys driver. A publicly available exploit exists, and it has been reported that the vulnerability might still be a 0-day exploit.
