Many chained compression pointers in a message results in a lot of CPU usage following them. A malicious actor with recursive-query access and control of an ordinarily delegated authority that serves specially crafted replies can exploit the vulnerability and degrade Unbound's general performance.","cvssScore":5.3,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","cwes":["CWE-770"],"vendors":[],"products":[],"references":[{"url":"https://www.nlnetlabs.nl/downloads/unbound/CVE-2026-96405.txt","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
