CVE-2016-4306

Multiple information leaks exist in various IOCTL handlers of the Kaspersky Internet Security KLDISK driver. Specially crafted IOCTL requests can cause the driver to return out-of-bounds kernel memory, potentially leaking sensitive information such as privileged tokens or kernel memory addresses that may be useful in bypassing kernel mitigations. An unprivileged user can run a program from user-mode to trigger this vulnerability.
