CVE-2012-3520
Publication date 3 October 2012
Last updated 24 July 2024
Ubuntu priority
Description
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.
From the Ubuntu Security Team
Pablo Neira Ayuso discovered a flaw in the credentials of netlink messages. An unprivileged local attacker could exploit this by getting a netlink based service, that relies on netlink credentials, to perform privileged actions.
