Description Mark J. Cox 2005-05-03 12:05:19 UTC 
+++ This bug was initially created as a clone of Bug #156683 +++

The (1) it87 and (2) via686a drivers in I2C for Linux 2.6.x before
2.6.11.8, and 2.6.12 before 2.6.12-rc2, create the sysfs "alarms" file
with write permissions, which allows local users to cause a denial of
service (CPU consumption) by attempting to write to the file, which
does not have an associated store function.
