{"id":"AZL-101592","summary":"CVE-2026-90025 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nusb: typec: ucsi: displayport: Fix OOB altmode array index\n\nThe UCSI displayport driver indexes the connector's port altmode array\nwith the GET_CURRENT_CAM response after checking it is not 0xff. The\nport altmode array is UCSI_MAX_ALTMODES elements long. If the PPM\nreturns an invalid GET_CURRENT_CAM response above UCSI_MAX_ALTMODES and\nnot equal to 0xff, the kernel may crash with an array index OOB error.\n\nUpdate the UCSI displayport driver to verify the current cam is less\nthan UCSI_MAX_ALTMODES before accessing the port altmode array.","modified":"2026-09-18T05:37:08Z","published":"2026-09-16T11:17:15Z","upstream":["CVE-2026-90025"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90025"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.150.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-101592.json"}}],"schema_version":"1.9.0"}
