Description Eugene Teo (Security Response) 2010-12-07 21:23:57 EST
The port data structure related to fc_host statistics collection is not initialized. This causes system crash when reading the fc_host statistics. The fix is to initialize port structure during driver attach.

This can be triggered by reading the fc statistics files under /sys/class/fc_host/host#/statistics.

A bfa adapter must be present in the system for the problem to occur.

Comment 3 Eugene Teo (Security Response) 2010-12-20 01:34:01 EST
Statement:

This issue did not affect the version of Linux kernel as shipped with Red Hat
Enterprise Linux 4 as it did not include support for the Brocade Fibre Channel Host Bus Adapter driver. It did not affect the version of Linux kernels as shipped with Red Hat Enterprise Linux 6 and Red Hat Enterprise MRG as they have the included the fix for this issue. A future kernel update in Red Hat Enterprise Linux 5 may address this flaw.
