  "summary": "ASoC: qcom: lpass-cpu: use DAI table index for playback constraints",
  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nASoC: qcom: lpass-cpu: use DAI table index for playback constraints\n\nThe DAI ID is a hardware port ID and is not necessarily the index of\nthe corresponding entry in variant->dai_driver.\n\nWhen configuring a DAI with LPAIF_I2SCTL_MODE_QUAD01, the probe code\ncurrently uses dai_id to index variant->dai_driver. This is incorrect\nfor platforms where DAI IDs are sparse. For example, the IPQ806x MI2S\nDAI has ID 4 while it is the only entry in the DAI driver table. If\nthat DAI is configured for QUAD01 and probe reaches this branch, the\ncode writes beyond that single entry via dai_driver[4] instead of\nupdating the DAI being processed.\n\nUse the loop index i when updating the current DAI's playback channel\nconstraints, while retaining dai_id for indexing the hardware-port\nspecific playback SD-line mode array.\n\nThis fixes the incorrect DAI table access for platforms where the DAI\nID does not match its position in the driver table.",
