CVE-2017-7346

Status Candidate

Overview

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.

Authored by Benjamin M. Romer

Andrey Konovalov discovered a use-after-free vulnerability in the DCCP implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly gain administrative privileges. It was discovered that the stack guard page for processes in the Linux kernel was not sufficiently large enough to prevent overlapping with the heap. An attacker could leverage this with another vulnerability to execute arbitrary code and gain administrative privileges. Various other vulnerabilities were addressed.
