Therefore a concurrent\nbind can change the device state between these operations, which can\nleave ioctl with a stale NULL gadget pointer and causing a NULL pointer\ndereference at gadget-\u003eops-\u003eioctl.\n\nRead dev-\u003egadget while holding dev-\u003elock so that the gadget pointer\nand device state are sampled consistently.","modified":"2026-09-18T05:37:08Z","published":"2026-09-16T11:17:14Z","upstream":["CVE-2026-90020"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90020"}],"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-101394.json"}}],"schema_version":"1.9.0"}
