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

ASoC: SOF: avoid a NULL dereference with unsupported widgets

If an IPC4 topology contains an unsupported widget, its .module_info field won't be set, then sof_ipc4_route_setup() will cause a kernel Oops trying to dereference it. Add a check for such cases.
