What is CVE-2016-4306?

The Kaspersky Internet Security driver contains multiple IOCTL handler vulnerabilities that can lead to information leaks. By sending specially crafted IOCTL requests, an attacker can induce the driver to expose out-of-bounds kernel memory. This memory may reveal sensitive information, such as privileged tokens or kernel memory addresses, which could enable an attacker to circumvent kernel protections. Critically, this vulnerability can be exploited by an unprivileged user running a program in user-mode, making it a serious security concern that requires prompt attention.
