CVE-2026-80911

Estado: RecibidaSin puntuar—

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

ASoC: SOF: sof-audio: Fix error path in sof_widget_setup_unlocked()

If either tplg_ops->dai_config or widget_kcontrol_setup fail during widget setup we would double decrement the use_count of the widget because the sof_widget_free_unlocked() would be called twice, similarly the core_put would be invoked twice as well.

Since the use_count and core_put() is handled within the widget_free function we need to return without falling through the pipe_widget_free label.

The fixes tag is picked to the last change around this part of the code which is adequately old enough for backporting purposes.
