## Overview

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

ASoC: SOF: Intel: hda-ipc: Do not process IPC reply before firmware boot

It is not yet clear, but it is possible to create a firmware so broken
that it will send a reply message before a FW_READY message (it is not
yet clear if FW_READY will arrive later).
Since the reply_data is allocated only after the FW_READY message, this
will lead to a NULL pointer dereference if not filtered out.

The issue was reported with IPC4 firmware but the same condition is present
for IPC3.

## Affected

- `linux_kernel >= 5.2, < 5.19.4`

## Remediation

Upgrade past the affected range:

- `linux_kernel 5.19.4`
