CWE-20  (opens in a new tab)

How to fix?

Upgrade torvalds/linux to version 4.10.8 or higher.

Overview

Affected versions of this package are vulnerable to Improper Input Validation. 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.
