A shared interrupt can\ntherefore enter the handler with dw_irq-\u003edw still NULL, leading to a\nNULL pointer dereference.\n\nSet the back pointer before installing each handler.","modified":"2026-09-17T14:15:23.217539632Z","published":"2026-09-16T11:17:10Z","upstream":["CVE-2026-89993"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-89993"}],"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-101423.json"}}],"schema_version":"1.9.0"}
