CWEhttps://cwe.mitre.org/data/definitions/287.html

The Netlink implementation in the Linux kernel before 3.2.30 does not properly handle messages that lack SCM_CREDENTIALS data, which might allow local users to spoof Netlink communication via a crafted message, as demonstrated by a message to (1) Avahi or (2) NetworkManager.

Weakness

When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct.
