Descriptions

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.

Existen múltiples fugas de información en varios manejadores IOCTL del controlador de Kaspersky Internet Security KLDISK. Peticiones IOCTL especialmente manipuladas pueden provocar que el controlador devuelva memoria del kernel fuera de límites, filtrando potencialmente información sensible como tokens privilegiados o direcciones de memoria kernel que podrían ser útiles en la elusión de mitigaciones del kernel. Un usuario no privilegiado puede ejecutar un programa desde el modo de usuario para desencadenar esta vulnerabilidad.
