Description Eugene Teo (Security Response) 2008-11-10 03:52:53 UTC 
Description of problem:
From: Johannes Berg <johannes>

If somebody sends an invalid beacon/probe response, that can trash the whole BSS descriptor. The descriptor is, luckily, large enough so that it cannot scribble past the end of it; it's well above 400 bytes long.

Comment 5 Eugene Teo (Security Response) 2008-12-05 05:32:04 UTC 
The driver was included in the upstream kernel since 2.6.22. We did not backport it to our RHEL kernels.
