{"id":"CVE-2026-98940","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-\u003edai_driver.\n\nWhen configuring a DAI with LPAIF_I2SCTL_MODE_QUAD01, the probe code\ncurrently uses dai_id to index variant-\u003edai_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.","modified":"2026-11-04T14:27:17.532731087Z","published":"2026-10-23T12:12:08.487Z","related":["SUSE-SU-2026:5091-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98940.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/63987bb73df65fb01245b5905b005aa47c1dd27a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6833f1893ac2ec40016c348779af63debf3700d2"},{"type":"WEB","url":"https://git.kernel.org/stable/c/69d2b7a4c115181629eb14d800aecc3e7de3f7fb"},{"type":"WEB","url":"https://git.kernel.org/stable/c/775df6a27e8433e2414124472938009b958f9a77"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c10823507a74d7474391c01121e3f59901b1789f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ca51771c8efde5df05476ac98dd1b2af4e2b149f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f11336e6d3cd9e28e5cdf1cb8a6171e7c3eff4e4"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98940.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98940"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"c223f41c1a52bfe10f1d3311679b1d1f9813e500"},{"fixed":"c10823507a74d7474391c01121e3f59901b1789f"},{"fixed":"63987bb73df65fb01245b5905b005aa47c1dd27a"},{"fixed":"775df6a27e8433e2414124472938009b958f9a77"},{"fixed":"6833f1893ac2ec40016c348779af63debf3700d2"},{"fixed":"69d2b7a4c115181629eb14d800aecc3e7de3f7fb"},{"fixed":"f11336e6d3cd9e28e5cdf1cb8a6171e7c3eff4e4"},{"fixed":"ca51771c8efde5df05476ac98dd1b2af4e2b149f"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-98940.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.14.0"},{"fixed":"5.15.224"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.191"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.160"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.113"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.56"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.10"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-98940.json"}}],"schema_version":"1.9.2"}
