Description Matthew Mosesohn 2011-08-25 16:35:46 UTC 
Description of problem:
This is occurring on many RHEL 6 systems:
SELinux has prevented ip from loading a kernel module. All confined programs
that need to load kernel modules should have already had policy written for
them. If a compromised application tries to modify the kernel this AVC will be
generated. This is a serious issue. Your system may very well be compromised.


Version-Release number of selected component (if applicable):
iproute-2.6.32-16.el6.x86_64
kernel-2.6.32-131.4.1.el6.x86_64
selinux-policy-3.7.19-93.el6_1.2.noarch

How reproducible:
Often, several times per day

Steps to Reproduce:
1. Try to connect to a VPN connection with NetworkManager
2.
3.
  
Actual results:
The connection fails

Expected results:
The connection should work

Additional info:
This happened only as a result of recent software updates in the past week.  This should be marked a regression.

Yes this is a kernel userspace issue that we will be covering up in 

selinux-policy-3.7.19-107.el6

Nothing was actually blocked.

If you want to try out the policy you can grab it from
