{"id":"AZL-110732","summary":"CVE-2026-98940 affecting package kernel 6.6.157.1-1","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":"2026-10-25T05:30:37Z","published":"2026-10-23T13:17:14Z","upstream":["CVE-2026-98940"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98940"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.157.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-110732.json"}}],"schema_version":"1.9.0"}
