Description Eugene Teo (Security Response) 2012-05-18 04:22:02 UTC 
Reported by Li Honggang (internal):
Attempting an rds connection from the IP address of an IPoIB interface to itself causes a kernel panic due to a BUG_ON() being triggered.  Making the test less strict allows rds-ping to work without crashing the machine.

A local unprivileged user could use this flaw to crash the sytem.

This issue did not affect the versions of the Linux kernel as shipped with Red Hat Enterprise Linux MRG. Future kernel updates for Red Hat Enterprise Linux 5 and 6 may address this issue.
