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.

Affected products

Linux kernel: through 2.6.30; 2.2.27, 2.4.36, 2.4.36.1, 2.4.36.2, 2.4.36.3, 2.4.36.4 (+310)
