This could lead to local escalation of privilege with no additional execution privileges needed.
MEDIUM 5.5EPSS 0.07%
Does this matter?
Lower severity and a low EPSS score (0.07%). Track it; it rarely justifies an emergency change on its own.
Description
In openMmapStream of AudioFlinger.cpp, there is a possible way to record audio without displaying the microphone privacy indicator due to a logic error in the code. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.
