Description Mark J. Cox (Product Security) 2006-01-11 05:22:24 EST
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:


We have not verified if this issue affects RHEL4.
Comment 2 David Miller 2006-01-11 18:39:26 EST
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 (Product Security) 2006-01-12 05:11:18 EST
Confirmed, commit of vulnerable code 20051110 therefore only affected 2.6.14+;
submitted clarfication to CVE project.
