CVE-2017-7346

Published: 30 March 2017

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.

From the Ubuntu Security Team

Li Qiang discovered that the DRM driver for VMware Virtual GPUs in the Linux kernel did not properly validate some ioctl arguments. A local attacker could use this to cause a denial of service (system crash).
