The\nsecond one is stored in port->netdev and later used by the remove path\nfor unregister_hdlc_device() and free_netdev().\n\nThis means that the registered netdev is not the same object that is\nunregistered and freed on remove. It also leaks the first allocation if\nthe second alloc_hdlcdev() call fails, and the first allocation is not\nchecked before ndev is used.\n\nOlder code allocated the HDLC netdev only once and stored the same object\nin both the local variable and port->netdev. The buggy conversion split\nthis into two alloc_hdlcdev() calls. A later rename changed the local\nvariable name to ndev, but the underlying mismatch remained.\n\nFix this by allocating the HDLC netdev only once and assigning the same\nobject to port->netdev.","published":"2026-08-15T06:21:15.000Z","lastModified":"2026-08-23T13:16:39.000Z","status":"Received","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":null,"cwe":[],"affected":[],"epss":{"score":0.00215,"percentile":0.11742,"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.
