CVE-2026-43137

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> ASoC: SOF: Intel: hda: Fix NULL pointer dereference<br /> <br /> If there&amp;#39;s a mismatch between the DAI links in the machine driver and<br /> the topology, it is possible that the playback/capture widget is not<br /> set, especially in the case of loopback capture for echo reference<br /> where we use the dummy DAI link. Return the error when the widget is not<br /> set to avoid a null pointer dereference like below when the topology is<br /> broken.<br /> <br /> RIP: 0010:hda_dai_get_ops.isra.0+0x14/0xa0 [snd_sof_intel_hda_common]
