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.

Comment 4 Petr Matousek 2012-06-05 18:04:54 UTC

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.
