The tool is still under development and is not yet publicly\navailable. Manual inspection confirms that the bug is still present in\nthe current wireless tree.\n\nAn x86_64 allyesconfig build showed no new warnings. As we do not have\ncompatible Libertas USB hardware for exercising this firmware-download\npath, no runtime testing was able to be performed.","published":"2026-08-10T13:20:35.000Z","lastModified":"2026-08-19T17:20:49.000Z","status":"Received","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":null,"cwe":[],"affected":[],"epss":{"score":0.00216,"percentile":0.1198,"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":"unknown","text":"Not yet scored.
