How to fix?

There is no fixed version for RHEL:6 kernel-debug-devel.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-debug-devel package and not the kernel-debug-devel package as distributed by RHEL. See How to fix? for RHEL:6 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.
