Descriptions
In drivers/char/virtio_console.c in the Linux kernel before 5.13.4, data corruption or loss can be triggered by an untrusted device that supplies a buf->len value exceeding the buffer size. NOTE: the vendor indicates that the cited data corruption is not a vulnerability in any existing use case; the length validation was added solely for robustness in the face of anomalous host OS behavior
** EN DISPUTA ** En el archivo drivers/char/virtio_console.c en el kernel de Linux versiones anteriores a 5.13.4, la corrupción o pérdida de datos puede ser desencadenada por un dispositivo no fiable que suministre un valor buf-)len excediendo el tamaño del buffer. NOTA: El proveedor indica que la citada corrupción de datos no es una vulnerabilidad en ningún caso de uso existente; la validación de la longitud se añadió únicamente para la robustez frente a un comportamiento anómalo del sistema operativo anfitrión.
