CVE-2006-2936 Possible DoS in write routine of ftdi_sio driver
Last modified: 2007-11-30 17:07:26 EST
Patch from Ian Abbott <email@example.com>
This patch limits the amount of outstanding 'write' data that can be queued up
for the ftdi_sio driver, to prevent userspace DoS attacks (or simple accidents)
that use up all the system memory by writing lots of data to the serial port.
