Details
A vulnerability classified as problematic has been found in Linux Kernel up to 4.10.5 (Operating System). Affected is the function vmw_surface_define_ioctl of the file drivers/gpu/drm/vmwgfx/vmwgfx_surface.c. The manipulation as part of a IOCTL Call leads to a input validation vulnerability. CWE is classifying the issue as CWE-20. The product receives input or data, but it does
not validate or incorrectly validates that the input has the
properties that are required to process the data safely and
correctly. This is going to have an impact on availability. CVE summarizes:
The vmw_surface_define_ioctl function in drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux kernel through 4.10.5 does not check for a zero value of certain levels data, which allows local users to cause a denial of service (ZERO_SIZE_PTR dereference, and GPF and possibly panic) via a crafted ioctl call for a /dev/dri/renderD* device.
