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