Descriptions

In QEMU 5.0.0 and earlier, es1370_transfer_audio in hw/audio/es1370.c does not properly validate the frame count, which allows guest OS users to trigger an out-of-bounds access during an es1370_write() operation.

En QEMU versión 5.0.0 y versiones anteriores, la función es1370_transfer_audio en el archivo hw/audio/es1370.c no comprueba apropiadamente el conteo de tramas, lo que permite a usuarios invitados del Sistema Operativo desencadenar un acceso fuera de límites durante una operación es1370_write().
