Descriptions

The ioresources_init function in kernel/resource.c in the Linux kernel through 4.7, as used in Android before 2016-08-05 on Nexus 6 and 7 (2013) devices, uses weak permissions for /proc/iomem, which allows local users to obtain sensitive information by reading this file, aka Android internal bug 28814213 and Qualcomm internal bug CR786116. NOTE: the permissions may be intentional in most non-Android contexts.

La función ioresources_init en kernel/resource.c en el kernel de Linux hasta la versión 4.7, como se usa en Android en versiones anteriores a 2016-08-05 en dispositivos Nexus 6 y 7 (2013), usa permisos débiles para /proc/iomem, lo que permite a usuarios locales obtener información sensible leyendo este archivo, también conocido como error interno de Android 28814213 y error interno de Qualcomm CR786116. NOTA: los permisos pueden ser intencionales en la mayoría de contextos distintos de Android.
