Name of the Vulnerable Software and Affected Versions ColorOS (affected versions not specified)

Description The issue is related to the surfaceflinger.CPP file in the ColorOS operating system, where an RGB value is defined on the stack but not initialized. This leads to information leakage when the screenShot function assigns a value to RGB, as uninitialized values on the stack are returned to attackers. The vulnerability can be exploited to bypass ALSR.
