Description Mark J. Cox 2006-01-11 10:22:24 UTC 
A netlink message with nlmsg_len set to 0 can cause an infinite loop holding the
netlink semaphore therefore allowing a local unprivileged DoS.

Here is the upstream fix for this issue:

http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=ad8e4b75c8a7bed475d72ce09bf526718862196

We have not verified if this issue affects RHEL4.
Comment 2 David Miller 2006-01-11 23:39:26 UTC 
Not relevant to any of our products, as the cleanup that introduced this
bug is not in any of our trees.
Comment 3 Mark J. Cox 2006-01-12 10:11:18 UTC 
Confirmed, commit of vulnerable code 20051110 therefore only affected 2.6.14+;
submitted clarfication to CVE project.
