Description Mark J. Cox 2005-10-10 12:14:18 UTC

mm/ioremap.c in Linux 2.6 on x86_64 systems allows local users to cause a denial
of service or an information leak via an iremap on a certain memory map that
causes the iounmap to perform a lookup of a page that does not exist.

fixed upstream in 2.6.12
