Description Mark J. Cox 2005-09-26 05:32:48 EDT
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.

Comment 5 Pete Zaitcev 2005-10-15 00:44:39 EDT
Regarding my proposal of checking if we still belong to the same process group
(or equivalent), it probably is not worth pursuing. Even if I were able to
work out kinks, it does not offer any decisive advantages over Linus' idea
of checking UID/EUID (as implemented by Harald).

committed in stream U4 build 34.11. A test kernel with this patch is available
