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.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/6833f1893ac2ec40016c348779af63debf3700d2","https://git.kernel.org/stable/c/69d2b7a4c115181629eb14d800aecc3e7de3f7fb","https://git.kernel.org/stable/c/775df6a27e8433e2414124472938009b958f9a77","https://git.kernel.org/stable/c/ca51771c8efde5df05476ac98dd1b2af4e2b149f","https://git.kernel.org/stable/c/f11336e6d3cd9e28e5cdf1cb8a6171e7c3eff4e4"],"products":[],"source":"nvd","synced_at":"2026-10-23T16:39:28.036610720+00:00"},"epss":{"cve":"CVE-2026-98940","score":0.00168,"percentile":0.06109,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
