Si bien la vulnerabilidad está en Oracle VM VirtualBox, los ataques pueden afectar significativamente a productos adicionales (cambio de alcance). Los ataques exitosos a esta vulnerabilidad pueden resultar en la adquisición de Oracle VM VirtualBox. CVSS 3.1 Puntuación base 8,8 (impactos en la confidencialidad, la integridad y la disponibilidad). Vector CVSS: (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H).

This vulnerability allows local attackers to escalate privileges on affected installations of Oracle VirtualBox. An attacker must first obtain the ability to execute high-privileged code on the target guest system in order to exploit this vulnerability.
The specific flaw exists within the VirtIOCore module. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a buffer. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of the hypervisor.
