Descriptions

Stack-based buffer overflow in the K7Sentry.sys kernel mode driver (aka K7AV Sentry Device Driver) before 12.8.0.119, as used in multiple K7 Computing products, allows local users to execute arbitrary code with kernel privileges via unspecified vectors.

Desbordamiento de buffer basado en pila en el controlador del modo de kernel K7Sentry.sys (también conocido como K7AV Sentry Device Driver) anterior a 12.8.0.119, utilizado en múltiples productos de K7 Computing, permite a usuarios locales ejecutar código arbitrario con privilegios de kernel a través de vectores no especificados.

Latest, and possibly earlier versions of K7Sentry.sys kernel mode driver, also named as the 'K7AV Sentry DeviceDriver', suffers from an out-of-bounds write condition that can be exploited locally by an attacker in order to execute code with kernel privileges. Successful exploitation of this bug results into vertical privilege escalation.
