Summary
ASoC: SOF: Intel: Fix NULL ptr dereference when ENOMEM
Details

In the Linux kernel, the following vulnerability has been resolved:

ASoC: SOF: Intel: Fix NULL ptr dereference when ENOMEM

Do not call snddmafreepages() when snddmaallocpages() returns -ENOMEM because it leads to a NULL pointer dereference bug.

The dmesg says:
