Description

A NULL pointer dereference was found in the Sound Open Firmware (SOF) driver. When a topology contains an unsupported widget type, the module_info field is NULL, and dereferencing it during route setup crashes the kernel.

Statement

This requires loading a malformed or incompatible audio topology file. Normal audio operation with supported hardware and topologies is unaffected. Custom topology development or testing scenarios are primarily at risk.
