This vulnerability allows local attackers to escalate privileges on vulnerable installations of Kingsoft Internet Security. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaws exists within the processing of IOCTL 0x80030004 or 0x80030008 by the KWatch3.sys (internet security) kernel driver. The issue lies in the failure to properly validate user-supplied data which can result in a kernel stack buffer overflow. An attacker can leverage this vulnerability to execute arbitrary code under the context of kernel.
