CVE-2025-41237

VMware ESXi, Workstation, and Fusion contain an integer-underflow in VMCI (Virtual Machine Communication Interface) that leads to an out-of-bounds write. A malicious actor with local administrative privileges on a virtual machine may exploit this issue to execute code as the virtual machine's VMX process running on the host. On ESXi, the exploitation is contained within the VMX sandbox whereas, on Workstation and Fusion, this may lead to code execution on the machine where Workstation or Fusion is installed.

Summary		(es) VMware ESXi, Workstation y Fusion presentan un subdesbordamiento de enteros en VMCI (Interfaz de Comunicación de Máquina Virtual) que provoca una escritura fuera de los límites. Un agente malicioso con privilegios de administrador local en una máquina virtual podría aprovechar este problema para ejecutar código como el proceso VMX de la máquina virtual que se ejecuta en el host. En ESXi, la explotación se realiza dentro del entorno de pruebas de VMX, mientras que en Workstation y Fusion puede provocar la ejecución de código en la máquina donde están instalados Workstation o Fusion.
