Description

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.
