ASoC: qcom: q6apm-lpass-dais: Fix NULL pointer dereference if source graph failed
FAQ
Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified, we will update the CVE to reflect this.

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 q6apm-lpass-dais 30000000.remoteproc:glink-edge:gpr:service@1:bedais: fail to start APM port 78 q6apm-lpass-dais 30000000.remoteproc:glink-edge:gpr:service@1:bedais: ASoC: error at snd_soc_pcm_dai_prepare on TX_CODEC_DMA_TX_3: -22 Unable to handle kernel NULL pointer dereference at virtual address 00000000000000a8 ...
