The RX, TX and event workers\nread their virtqueue before locking and checking the corresponding flag,\nso a worker delayed across freeze and restore can observe the replacement\nqueue's running state while retaining a pointer to the deleted queue.\n\nRead each virtqueue under its mutex after checking the run flag, keeping\nthe pointer and state in the same queue generation.","modified":"2026-08-30T05:26:50Z","published":"2026-08-22T16:16:34Z","upstream":["CVE-2026-74614"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-74614"}],"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-97226.json"}}],"schema_version":"1.9.0"}
