CVE-2017-7294
HighSummary
The vmw_surface_define_ioctl function in the Linux kernel up to version 4.10.6 does not validate the addition of certain levels data, allowing local users to trigger an integer overflow and out-of-bounds write. This can lead to system hang or crash, and potentially privilege escalation.
Risk Assessment
This vulnerability poses a risk of system failure and the potential for local users to escalate privileges, which can lead to serious security implications for the organization.
Recommendation
It is recommended to update the Linux kernel to version 4.10.7 or later to mitigate this vulnerability and implement additional security measures for local users.

Original NVD description (English source)
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.
