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

A flaw was found in the Linux kernel's Advanced Linux Sound Architecture on Chip (ASoC) Sound Open Firmware (SOF) Intel High Definition Audio (HDA) subsystem. This flaw occurs when there is a mismatch between the Digital Audio Interface (DAI) links in the machine driver and the audio topology, leading to a playback/capture widget not being set. This can result in a null pointer dereference, potentially causing a system crash or denial of service.
