Description Eugene Teo (Security Response) 2011-01-07 03:52:26 EST
Enable the port when disabling countermeasures, and disable it on enabling countermeasures.
            
This bug causes the response of the system to certain attacks to be ineffective.
                        
It also prevents wpa_supplicant from getting scan results, as wpa_supplicant disables countermeasures on startup - preventing the hardware from scanning.
                                        
wpa_supplicant works with ap_mode=2 despite this bug because the commit handler re-enables the port.
                                                    
The log tends to look like:
                                                            
State: DISCONNECTED -> SCANNING

Comment 3 Eugene Teo (Security Response) 2011-01-11 03:58:14 EST
Statement:

This issue did not affect the version of Linux kernel as shipped with Red Hat
Enterprise Linux 4 and 5 as they did not backport the upstream commit d03032af that introduced this issue. Future kernel updates in Red Hat Enterprise Linux 6 and Red Hat Enterprise MRG may address this flaw.
