{"schema":"threatline.record/2","record":{"id":"CVE-2026-98940","aliases":[],"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.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98940","source_modified_at":"2026-10-23T12:12:08.487Z","fetched_at":"2026-10-23T18:42:43.628194Z","product":"Linux","vendor":"Linux","versions":[{"version":"c223f41c1a52bfe10f1d3311679b1d1f9813e500","lessThan":"775df6a27e8433e2414124472938009b958f9a77","status":"affected","versionType":"git"},{"version":"c223f41c1a52bfe10f1d3311679b1d1f9813e500","lessThan":"6833f1893ac2ec40016c348779af63debf3700d2","status":"affected","versionType":"git"},{"version":"c223f41c1a52bfe10f1d3311679b1d1f9813e500","lessThan":"69d2b7a4c115181629eb14d800aecc3e7de3f7fb","status":"affected","versionType":"git"},{"version":"c223f41c1a52bfe10f1d3311679b1d1f9813e500","lessThan":"f11336e6d3cd9e28e5cdf1cb8a6171e7c3eff4e4","status":"affected","versionType":"git"},{"version":"c223f41c1a52bfe10f1d3311679b1d1f9813e500","lessThan":"ca51771c8efde5df05476ac98dd1b2af4e2b149f","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98940","source_modified_at":"2026-10-23T12:12:08.487Z","fetched_at":"2026-10-23T18:42:43.628194Z","product":"Linux","vendor":"Linux","versions":[{"version":"5.14","status":"affected"},{"version":"0","lessThan":"5.14","status":"unaffected","versionType":"semver"},{"version":"6.6.160","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.113","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.56","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.10","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}],"defaultStatus":"affected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98940","source_modified_at":"2026-10-23T12:12:08.487Z","fetched_at":"2026-10-23T18:42:43.628194Z","package":{"name":"Linux","ecosystem":null},"version":"775df6a27e8433e2414124472938009b958f9a77","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98940","source_modified_at":"2026-10-23T12:12:08.487Z","fetched_at":"2026-10-23T18:42:43.628194Z","package":{"name":"Linux","ecosystem":null},"version":"6833f1893ac2ec40016c348779af63debf3700d2","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98940","source_modified_at":"2026-10-23T12:12:08.487Z","fetched_at":"2026-10-23T18:42:43.628194Z","package":{"name":"Linux","ecosystem":null},"version":"69d2b7a4c115181629eb14d800aecc3e7de3f7fb","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":null,"percentile":null,"score_date":null},"published_at":"2026-10-23T12:12:08.487Z","modified_at":"2026-10-23T12:12:08.487Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-98940","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23T12:12:08.487Z"}],"sources":["CVE List"],"references":[{"source":"CVE List","url":"https://git.kernel.org/stable/c/775df6a27e8433e2414124472938009b958f9a77"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/6833f1893ac2ec40016c348779af63debf3700d2"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/69d2b7a4c115181629eb14d800aecc3e7de3f7fb"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/f11336e6d3cd9e28e5cdf1cb8a6171e7c3eff4e4"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/ca51771c8efde5df05476ac98dd1b2af4e2b149f"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-23T12:12:08.487Z","content_hash":"507e2df64bbc7667c662a8aeeff814efec66d504ca81644c349bec17b72ff480"}}
