"value": "The ARM-based hardware debugging feature on Raspberry Pi 3 module B+ and possibly other devices allows non-secure EL1 code to read/write any EL3 (the highest privilege level in ARMv8) memory/register via inter-processor debugging. With a debug host processor A running in non-secure EL1 and a debug target processor B running in any privilege level, the debugging feature allows A to halt B and promote B to any privilege level. As a debug host, A has full control of B even if B owns a higher privilege level than A. Accordingly, A can read/write any EL3 memory/register via B. Also, with this memory access, A can execute arbitrary code in EL3."

"value": "La funcionalidad de depuraci\u00f3n de hardware basada en ARM en el m\u00f3dulo B+ de Raspberry Pi 3 y, posiblemente otros dispositivos, permite que un c\u00f3digo EL1 inseguro lea/escriba cualquier memoria/registro EL3 (el nivel de privilegios m\u00e1s alto en ARMv8) mediante un proceso de depuraci\u00f3n de interprocesador. Con un procesador de depuraci\u00f3n host \"A\" que opera con c\u00f3digo EL1 inseguro y un procesador de depuraci\u00f3n objetivo B que opera con cualquier nivel de privilegios, la funcionalidad de depuraci\u00f3n permite a \"A\" detener \"B\" y asciende \"B\" a cualquier nivel de privilegios. Como host de depuraci\u00f3n, A tiene el control total sobre B aunque B posee a nivel de privilegios m\u00e1s alto que A. Por consiguiente, A puede leer/escribir cualquier memoria/registro EL3 a trav\u00e9s de B. Asimismo, con este acceso a la memoria, A puede ejecutar c\u00f3digo arbitrario en EL3 tambi\u00e9n."
