Description Eugene Teo (Security Response) 2010-11-09 05:57:03 UTC 
Description of problem:
INET-DIAG is inconsistent about how it looks up the bytecode contained in a
netlink message, making it possible for a user to cause the kernel to execute
unaudited INET-DIAG bytecode. This can be abused to make the kernel enter an infinite loop, and possibly other consequences.

Comment 3 Eugene Teo (Security Response) 2010-11-22 06:06:33 UTC 
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 monitoring of INET transport protocol sockets. Future updates in Red Hat Enterprise Linux 5, 6 and Red Hat Enterprise MRG may address this flaw.
