As I mentioned in comment #10, this is not an exhaustive list of modules to blacklist. On my test Red Hat Enterprise Linux 5 machine, the sctp module does not load automatically when the reproducer is executed. But yes, I will include your suggestion to the existing mitigation steps.

For every security bug, we have a top-level bug (this one) and several tracking bugs. The top-level bug is only used for tracking purposes, so the status for the top-level bug should not be taken as an indication for anything. Only the status of the tracking bugs matter.
