Processing the leak break might take a reference to\nthe tcon in cached_dir_lease_break() and then fail to release the ref in\ncached_dir_offload_close, since cfid-\u003etcon is still NULL.","modified":"2026-04-01T05:18:27.895543Z","published":"2024-12-29T12:15:07Z","upstream":["CVE-2024-56729"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-56729"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6.64.2-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-54999.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
