Description

Microsoft Windows is prone to a local privilege-escalation vulnerability that occurs in the Windows kernel due to a NULL-pointer dereference error. A local attacker can exploit this issue to execute arbitrary code with kernel-level privileges. Successful exploits will result in the complete compromise of affected computers. Failed exploit attempts may cause a denial-of-service condition.
