This prevents a\npossible buffer overflow when copying data from potentially malicious\nX.509 certificate fields that can be arbitrarily large, such as ASN.1\nINTEGER serial numbers, issuer names, etc.","modified":"2026-04-01T05:22:15.642454Z","published":"2025-12-24T11:16:01Z","upstream":["CVE-2025-68724"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-68724"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6.121.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-73159.json"}}],"schema_version":"1.7.5"}
