Users of crates.io are **not affected**, as crates.io forbids uploading crates containing any symlink.","modified":"2026-09-20T05:33:47Z","published":"2026-05-25T10:16:15Z","upstream":["CVE-2026-5223"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-5223"}],"affected":[{"package":{"name":"rust","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/rust"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.75.0-30"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-88272.json"}}],"schema_version":"1.9.0"}
