But in\nthis process, another receiver of this notification can veto the\nregistration. The netdev registration will be aborted because of this veto.\n\nThe register_netdevice() call will try to clean up the net_device using\nunregister_netdevice_queue() - which only uses the .priv_destructor to\nfree private resources. In this situation, .dellink will not be called.\n\nThe cleanup of the untagged batadv_meshif_vlan must thefore be done in the\ndestructor to avoid a leak of this object.","published":"2026-08-15T06:21:50.000Z","lastModified":"2026-08-17T06:18:24.000Z","status":"Received","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":null,"cwe":[],"affected":[],"epss":{"score":0.0022,"percentile":0.12395,"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.
