Insight

Insight

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.

Solution

Solution

Run yum update kernel to update your system. You will need to reboot your system in order for the new kernel to be running.
