{"id":"AZL-91710","summary":"CVE-2026-14258 affecting package dhcpcd for versions less than 10.0.8-4","details":"A flaw was found in dhcpcd's IPv6 Neighbor Discovery Router Advertisement processing. A specially crafted IPv6 Router Advertisement containing a zero-length Neighbor Discovery option can bypass validation during packet storage and later be reparsed without adequate validation, causing the parser to enter a non-advancing loop. Successful exploitation may result in excessive CPU consumption, leading to a denial of service.","modified":"2026-08-30T05:26:50Z","published":"2026-07-01T11:16:25Z","upstream":["CVE-2026-14258"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-14258"}],"affected":[{"package":{"name":"dhcpcd","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/dhcpcd"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"10.0.8-4"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-91710.json"}}],"schema_version":"1.9.0"}
