      "value": "Software installed and run as a non-privileged user may conduct improper GPU system calls to cause an integer overflow and map two GPU virtual addresses to the same physical address. One of these virutal mappings can be freed along with the physical page, allowing for a read/write UAF via the second mapping\n\n\n\nThe second virtual mapping references a physical address that has been freed after the first virtual mapping has been freed. This allows the physical memory to be allocated (for example) by another process and read/written to."

      "value": "El software instalado y ejecutado como un usuario no privilegiado puede realizar llamadas al sistema de GPU impropias para causar un desbordamiento de entero y mapear dos direcciones virtuales de GPU a la misma dirección física. Uno de estos mapeos virtuales puede ser liberado junto con la página física, permitiendo un UAF de lectura/escritura a través del segundo mapeo.\n\nEl segundo mapeo virtual hace referencia a una dirección física que ha sido liberada después de que el primer mapeo virtual haya sido liberado. Esto permite que la memoria física sea asignada (por ejemplo) por otro proceso y se lea/escriba en ella."
