  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nASoC: SOF: ipc4-topology: Refresh copier IPC payload before widget setup\n\nThe ipc_config_data buffer for copier widgets is built once during\nipc_prepare (called from sof_pcm_setup_connected_widgets) and cached\nfor reuse. For host copiers this buffer contains the copier_data with\ngtw_cfg.node_id (host DMA ID). For DAI copiers it additionally includes\na dma_config_tlv trailer with stream_id and dma_channel_id for HDA link\nDMA.\n\nOn suspend/resume, both host and link DMA streams are released and\nre-allocated with potentially different stream tags. The underlying\ncopier_data and dma_config_tlv structures are correctly updated by\nhost_config and sdw_hda_dai_hw_params respectively. However, since the\nwidget list (spcm-\u003estream[].list) persists across suspend,\nsof_pcm_hw_params skips sof_pcm_setup_connected_widgets and ipc_prepare\nnever runs again to rebuild ipc_config_data. The stale cached payload\nis then sent to firmware with boot-time DMA channel assignments, causing\nDMA channel conflicts that lead to firmware errors and crashes.\n\nFix this by refreshing copier_data and dma_config_tlv portions of\nipc_config_data in sof_ipc4_widget_setup right before the IPC message\nis sent. This ensures the payload always reflects the current DMA state\nregardless of whether ipc_prepare ran.\n\nFor DAI copiers, the gtw_cfg.config_length in copier_data is temporarily\ninflated to include the TLV size (matching the ipc_config_data layout)\nbefore copying, then restored, mirroring what\nsof_ipc4_prepare_copier_module does when first building the buffer.",
