Remove the QP from the xarray\nbefore dropping the destroy-path reference so no new lookup can acquire\nit while destruction waits for existing users.","modified":"2026-09-18T14:16:29.884688768Z","published":"2026-09-17T17:17:28Z","upstream":["CVE-2026-90308"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90308"}],"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-102026.json"}}],"schema_version":"1.9.0"}
