      "value": "Software installed and run as a non-privileged user may conduct improper GPU system calls to cause an error path leading to UAF of GPU page tables.\n\n\n\nThe vulnerability allows physical memory allocated for MMU page tables to be used after being freed. This was caused by an error path that would not cleanup properly before freeing the physical allocation."

      "value": "El software instalado y ejecutado como un usuario no privilegiado puede realizar llamadas al sistema de GPU impropias para provocar una ruta de error que lleva a UAF de las tablas de páginas de la GPU.\n\nLa vulnerabilidad permite que la memoria física asignada para las tablas de páginas de la MMU sea utilizada después de ser liberada. Esto fue provocado por una ruta de error que no realizaba una limpieza adecuada antes de liberar la asignación física."
