This will cause the incoming call to be aborted.","modified":"2026-04-01T05:22:48.640537Z","published":"2025-08-16T11:15:44Z","upstream":["CVE-2025-38514"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-38514"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:2","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.15.200.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-75087.json"}}],"schema_version":"1.7.5"}
