NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-modules-extra package and not the kernel-modules-extra package as distributed by Oracle. See How to fix? for Oracle:9 relevant fixed versions and status.

A flaw was found in the Framebuffer Console (fbcon) in the Linux Kernel. When providing font->width and font->height greater than 32 to fbcon_set_font, since there are no checks in place, a shift-out-of-bounds occurs leading to undefined behavior and possible denial of service.
