Introduce xdp_sock::drain_cont and act\nupon this flag - when it is set, keep on consuming descriptors from\nAF_XDP Tx ring and put them directly onto Cq. Previously these\ndescriptors were silently lost and could never be reached again.","modified":"2026-08-31T05:26:27Z","published":"2026-08-15T13:18:01Z","upstream":["CVE-2026-74559"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-74559"}],"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-96483.json"}}],"schema_version":"1.9.0"}
