This leaves stale\ngateway state behind across cleanup and can break a later mesh recreation.\n\nClear bat_priv-\u003egw.curr_gw before walking the gateway list so the selected\ngateway reference is dropped as part of teardown.","modified":"2026-08-28T17:48:11.545278226Z","published":"2026-06-24T08:16:22Z","upstream":["CVE-2026-52926"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-52926"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6.143.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-90440.json"}}],"schema_version":"1.9.0"}
