Title
ASoC: qcom: q6apm-lpass-dais: Fix NULL pointer dereference if source graph failed
Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: qcom: q6apm-lpass-dais: Fix NULL pointer dereference if source graph failed
If earlier opening of source graph fails (e.g. ADSP rejects due to
incorrect audioreach topology), the graph is closed and
"dai_data->graph[dai->id]" is assigned NULL. Preparing the DAI for sink
graph continues though and next call to q6apm_lpass_dai_prepare()
receives dai_data->graph[dai->id]=NULL leading to NULL pointer
exception:
qcom-apm gprsvc:service:2:1: Error (1) Processing 0x01001002 cmd
qcom-apm gprsvc:service:2:1: DSP returned error[1001002] 1
