CVE-2026-93187

Estado: RecibidaSin puntuar—

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.
