Detailsinfo

A vulnerability, which was classified as problematic, was found in Linux Kernel up to 4.10.6 (Operating System). This affects 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 out-of-bounds write vulnerability. CWE is classifying the issue as CWE-787. The product writes data past the end, or before the beginning, of the intended buffer. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

The vmw_surface_define_ioctl function in drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux kernel through 4.10.6 does not validate addition of certain levels data, which allows local users to trigger an integer overflow and out-of-bounds write, and cause a denial of service (system hang or crash) or possibly gain privileges, via a crafted ioctl call for a /dev/dri/renderD* device.
