It's OK for the devices\nthe driver itself creates at the module probe time, but if the device\nis bound manually via sysfs interface, this could be -1 as \"none\", and\nthis leads to OOB access for index[] and other parameters.\n\nAdd a sanity check for the card index and warn/correct it if it's a\nvalue out of the range.","modified":"2026-09-12T14:15:30.115807668Z","published":"2026-09-11T20:19:02Z","upstream":["CVE-2026-80965"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-80965"}],"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-100686.json"}}],"schema_version":"1.9.0"}
