Severity High
Score 7.5/10


The BnGraphicBufferProducer::onTransact function in libs/gui/IGraphicBufferConsumer.cpp in mediaserver in Android 4.x before 4.4.4, 5.x before 5.1.1 LMY49H, and 6.x before 2016-03-01 does not initialize a certain output data structure, which allows attackers to obtain sensitive information, and consequently bypass an unspecified protection mechanism, by triggering a QUEUE_BUFFER action, as demonstrated by obtaining Signature or SignatureOrSystem access, aka internal bug 26338109.
