Although the issue below is for linux-2.6 the code in linux-2.4 looks pretty much identical so this issue may affect RHEL2.1 +++ This bug was initially created as a clone of Bug #169260 +++ Harald Welte mailed the lkml on 20050925 with a report of how to cause a local oops if a user has permissions to access an arbitrary usb device. I've rated this as 'moderate' instead of 'important' due to that requirement. Although usb permissions will be given automatically to console users, a DOS from a user who has physical access to a machine is little extra risk and we ignore that from the severity calculation. See the following URL for the description and patch http://marc.theaimsgroup.com/?l=linux-kernel&m=112766129313883
doesn't look like we have a reproducer for this one, but the patch is there.. looks to be a well-understood problem and has been upstream for a while.
