Vulnerability description

The vulnerability allows a local user to gain elevated privileges on the target system.

The weakness is due to improper handling of objects in memory by win32k.sys. By sending a specially crafted system call NtSetWindowLongPtr(), a local attacker can set index GWLP_ID to WS_CHILD value on a window handle with GWL_STYLE and execute arbitrary code with system privileges.

Successful explotation of the vulnerability results in privilege escalation.

Note: this vulnerability is being actively exploited in the wild.
