It should not be\nnecessary to check console_is_registered() here since the function\nshould not be called in the fist place when the console is not\nregistered.","modified":"2026-09-19T05:33:49Z","published":"2026-09-17T17:17:08Z","upstream":["CVE-2026-90158"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90158"}],"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-102012.json"}}],"schema_version":"1.9.0"}
