{"id":"CVE-2026-98940","published":"2026-10-23T13:17:14.960","lastModified":"2026-10-23T13:17:14.960","description":"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.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/6833f1893ac2ec40016c348779af63debf3700d2","tags":[]},{"url":"https://git.kernel.org/stable/c/69d2b7a4c115181629eb14d800aecc3e7de3f7fb","tags":[]},{"url":"https://git.kernel.org/stable/c/775df6a27e8433e2414124472938009b958f9a77","tags":[]},{"url":"https://git.kernel.org/stable/c/ca51771c8efde5df05476ac98dd1b2af4e2b149f","tags":[]},{"url":"https://git.kernel.org/stable/c/f11336e6d3cd9e28e5cdf1cb8a6171e7c3eff4e4","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
