The string argument must be a well-formed MAC-48 address in one of the supported formats, but this requirement has been poorly documented.  If an application calls the function with an argument that deviates from the expected format, the function can read data beyond the end of the provided string and write data beyond the end of the allocated buffer.","published":"2025-12-31T01:15:55.000Z","lastModified":"2026-06-17T08:31:29.000Z","status":"Deferred","sourceIdentifier":"security@tcpdump.org","cvss":{"version":"3.1","score":1.9,"severity":"LOW","vector":"CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:U/C:N/I:L/A:N"},"cwe":["CWE-122","CWE-126"],"affected":[],"epss":{"score":0.00117,"percentile":0.01687,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.12%).
