Number of envelopes is becoming zero because of erroneous input stream.Inside SBR start band and stop band are calculated based on number of envelope's. In this case start bands is becoming negative. In sbr processing buffer is accessed from start to stop band. This is causing OOB read access Bug:113037143 Test: poc Change-Id: Iade10e8cb86676784703e7226b7e132761eb12b1
