>From CAN-2005-3055:

Linux kernel 2.6.8 to 2.6.14-rc2 allows local users to cause a denial
of service (kernel OOPS) via a userspace process that issues a USB
Request Block (URB) to a USB device and terminates before the URB is
finished, which leads to a stale pointer reference.

I believe that the 2.6.12 and 2.6.13 kernels have this problem.
2.6.8 and 2.4.27 do not seem to have it as the driver is missing.

Upstream do not seem to have a solution (See [3] above) yet, 
but I expect it will show up in 2.6-stable when they do.
