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 "daidata->graph[dai->id]" is assigned NULL. Preparing the DAI for sink graph continues though and next call to q6apmlpassdaiprepare() receives dai_data->graph[dai->id]=NULL leading to NULL pointer exception:
