Description
Description
In the Linux kernel, the following vulnerability has been resolved:
ASoC: SOF: ipc4-topology: Return error for invalid number of formats
When the number of input or output formats is zero,
sof_ipc4_widget_setup_comp_src() and sof_ipc4_widget_setup_comp_asrc()
print an error and jump to the cleanup label. At that point 'ret' is
still 0, because the earlier sof_ipc4_get_audio_fmt() call succeeded, so
the function returns success and the caller never finds out that the
widget setup actually failed.
Set ret to -EINVAL before the goto so the error gets reported.
