Use tty_port_tty_get()/tty_kref_put() to hold a proper reference\nfor the duration the tty pointer is needed.","modified":"2026-08-30T05:26:50Z","published":"2026-08-22T16:16:41Z","upstream":["CVE-2026-74675"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-74675"}],"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-97235.json"}}],"schema_version":"1.9.0"}
