CVE-2012-6689

Published: 31 December 2012

The netlink_sendmsg function in net/netlink/af_netlink.c in the Linux kernel before 3.5.5 does not validate the dst_pid field, which allows local users to have an unspecified impact by spoofing Netlink messages.

From the Ubuntu security team

A flaw was discovered in how netlink sockets validate message origins. A local attacker could exploit this flaw to send netlink message notifications, with spoofed credentials, to subscribed tasks.
