This releases the reference on all subsequent\nprobe failures and on driver detach.\n\nFound by code review.","modified":"2026-09-13T06:06:36Z","published":"2026-09-11T20:19:28Z","upstream":["CVE-2026-89473"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-89473"}],"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-100322.json"}}],"schema_version":"1.9.0"}
