Descriptions

In ColorOS (oppo mobile phone operating system, based on AOSP frameworks/native code position/services/surfaceflinger surfaceflinger.CPP), RGB is defined on the stack but uninitialized, so when the screenShot function to RGB value assignment, will not initialize the value is returned to the attackers, leading to values on the stack information leakage, the vulnerability can be used to bypass attackers ALSR.

En ColorOS (sistema operativo de telefonía móvil oppo, basado en código surfaceflinger.CPP de position/services/surfaceflinger del frameworks/native de AOSP), RGB es definido en la pila (stack) pero no es inicializado, por eso cuando la función screenShot en la asignación del valor de RGB, no inicializará el valor que es devuelto a los atacantes, conllevando a que unos valores en la pila filtren información, la vulnerabilidad puede ser usada para omitir la funcionalidad ALSR por los atacantes.
