CVE-2009-1192 Information

Description

The (1) agp_generic_alloc_page and (2) agp_generic_alloc_pages functions in drivers/char/agp/generic.c in the agp subsystem in the Linux kernel before 2.6.30-rc3 do not zero out pages that may later be available to a user-space process which allows local users to obtain sensitive information by reading these pages.
