Description
The vulnerability allows a local attacker to obtain elevated privileges on the target system.
The weakness exists due to improper handling of Dynamic Data Exchange objects by the kernel-mode driver (win32k.sys). A local attacker can run a specially crafted application to gain elevated privileges and execute arbitrary code with SYSTEM privileges.
Successful exploitation of the vulnerability results in arbitrary code execution on the vulnerable system.
