Worse, the int\nreturn value (0 on success, negative errno on failure) was assigned to\nthe unsigned long enable flag, inverting the intended logic: a valid\nnumber was treated as \"disable\" while a parse failure enabled FCE.\n\nParse the value into enable and propagate parse errors to userspace.","modified":"2026-10-02T14:15:37.590134360Z","published":"2026-09-16T11:16:52Z","upstream":["CVE-2026-89851"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-89851"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6.157.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-101399.json"}}],"schema_version":"1.9.2"}
