Descriptions

Local attackers can trigger a Kernel Pool Buffer Overflow in Antiy AVL ATool v1.0.0.22. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the processing of IOCTL 0x80002004 by the ssdt.sys kernel driver. The bug is caused by failure to properly validate the length of the user-supplied data. An attacker can leverage this vulnerability to execute arbitrary code in the context of the kernel, which could lead to privilege escalation. A failed exploit could lead to denial of service.

Los atacantes locales pueden desencadenar un desbordamiento de búfer del grupo del kernel en Antiy AVL ATool v1.0.0.22. En primer lugar, un atacante debe obtener la capacidad de ejecutar código de bajos privilegios en el sistema objetivo para explotar esta vulnerabilidad. Este error en concreto existe al procesar el IOCTL 0x80002004 por el controlador del kernel ssdt.sys. El error proviene del error a la hora de validar correctamente la longitud de los datos proporcionados por el usuario. Un atacante puede aprovechar esta vulnerabilidad para ejecutar código arbitrario en el contexto del kernel, lo que podría conducir al escalado de privilegios. Un error en la explotación podría conducir a una denegación de servicio (DoS).
