CVE-2026-80581: ASoC: SOF: ipc4-pcm: Continue the pipeline trigger in case of IPC timeout

[Greg Kroah-Hartman]

From: Greg Kroah-Hartman <gregkh@kernel.org>

Description
===========

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

ASoC: SOF: ipc4-pcm: Continue the pipeline trigger in case of IPC timeout

Ignore IPC errors for pipeline state change if the firmware state is
crashed or the IPC has timed out.

If the firmware has crashed the kernel still needs to go through the state
changes to reset its internal to be able to correctly work the next time
the DSP is booted up.

The case with IPC timeout is a bit more problematic, but it has been
rootcaused to be the result of system scheduling blockage and the firmware
did actually received and handled the message, but the reply handling got
blocked by issues outside of the SOF stack.
So far the best way to handle this is to continue with setting the state.

The Linux kernel CVE team has assigned CVE-2026-80581 to this issue.

Mitigation
==========

The Linux kernel CVE team recommends that you update to the latest
stable kernel version for this, and many other bugfixes.  Individual
changes are never tested alone, but rather are part of a larger kernel
release.  Cherry-picking individual commits is not recommended or
supported by the Linux kernel community at all.  If however, updating to
the latest release is impossible, the individual changes to resolve this
issue can be found at these commits:
