Como sucede cada mes Google ha liberado la OTA de actualización correspondiente al mes de Mayo 2016 en donde parcha 25 vulnerabilidades de seguridad que afectan a sus dispositivos.
Junto con la OTA podemos encontrar un boletín que indica qué fallos de seguridad han sido arreglados en donde la más grave vulnerabilidad permite ejecución de código remoto a través de múltiples métodos como correos, navegación web y MMS.
En la siguiente tabla podemos observar las seis vulnerabilidades de gravedad critica, 12 altas, seis moderadas y una menor que se han arreglado y porqué afectaban la seguridad de Android.
