There is no fixed version for Centos:7 kernel-bootwrapper.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-bootwrapper package and not the kernel-bootwrapper package as distributed by Centos. See How to fix? for Centos:7 relevant fixed versions and status.

The vmw_gb_surface_define_ioctl function in drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux kernel through 4.10.7 does not validate certain levels data, which allows local users to cause a denial of service (system hang) via a crafted ioctl call for a /dev/dri/renderD* device.
