Description Eugene Teo (Security Response) 2010-03-23 02:33:11 UTC 
Description of problem:
When creating a high number of Bluetooth sockets (L2CAP, SCO and RFCOMM) it is possible to scribble repeatedly on arbitrary pages of memory. Ensure that the content of these sysfs files is always less than one page. Even if this means truncating. The files in question are scheduled to be moved over to debugfs in
the future anyway.
