Technical details
An elevation of privilege vulnerability in the Windows Kernel's object memory handling allows a locally authenticated attacker to execute arbitrary code with elevated permissions. The vulnerability requires local access and execution of a specially crafted application; it cannot be exploited remotely. The kernel fails to properly validate or sanitize objects in memory, permitting privilege escalation.
