All other error paths in the\nfunction jump to the cleanup label that ends with\nmlxsw_sp_lag_put(), so this is a single missed release.\n\nFix the leak by replacing the bare 'return err' with a goto to the\nexisting error cleanup label, which will drop the reference safely.","published":"2026-08-15T06:22:04.000Z","lastModified":"2026-08-23T13:16:43.000Z","status":"Received","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":null,"cwe":[],"affected":[],"epss":{"score":0.0022,"percentile":0.12448,"date":"2026-10-27","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.
