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

ASoC: SOF: ipc4-topology: Refresh copier IPC payload before widget setup

The ipc_config_data buffer for copier widgets is built once during ipc_prepare (called from sof_pcm_setup_connected_widgets) and cached for reuse. For host copiers this buffer contains the copier_data with gtw_cfg.node_id (host DMA ID). For DAI copiers it additionally includes a dma_config_tlv trailer with stream_id and dma_channel_id for HDA link DMA.

On suspend/resume, both host and link DMA streams are released and re-allocated with potentially different stream tags. The underlying copier_data and dma_config_tlv structures are correctly updated by host_config and sdw_hda_dai_hw_params respectively. However, since the widget list (spcm->stream[].list) persists across suspend, sof_pcm_hw_params skips sof_pcm_setup_connected_widgets and ipc_prepare never runs again to rebuild ipc_config_data. The stale cached payload is then sent to firmware with boot-time DMA channel assignments, causing DMA channel conflicts that lead to firmware errors and crashes.

Fix this by refreshing copier_data and dma_config_tlv portions of ipc_config_data in sof_ipc4_widget_setup right before the IPC message is sent. This ensures the payload always reflects the current DMA state regardless of whether ipc_prepare ran.

For DAI copiers, the gtw_cfg.config_length in copier_data is temporarily inflated to include the TLV size (matching the ipc_config_data layo…

WID-SEC-W-2026-3042 — Linux Kernel: Mehrere Schwachstellen

Ein Angreifer kann mehrere Schwachstellen im Linux Kernel ausnutzen, um einen nicht näher spezifizierten Angriff durchzuführen, darunter möglicherweise die Ausführung von beliebigem Code, die Ausweitung von Berechtigungen, die Offenlegung von Informationen, die Manipulation von Daten oder Denial-of-Service-Zustände.
