**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** The issue occurs when the system is suspended while audio is active, causing the `sof ipc4 pcm hw free()` function to reset the pipelines. If the firmware crashes during audio playback or when resetting the stream before suspend, the `sof ipc4 set multi pipeline state()` function will fail with an IPC error, interrupting the state change. This misalignment between the kernel and firmware state can result in errors returned by firmware for IPC messages, eventually failing the audio resume. The kernel state will be corrected on the next DSP boot after the DSP panic. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
