CVE-2017-7346

La función vmw_gb_surface_define_ioctl en drivers/gpu/drm/vmwgfx/vmwgfx_surface.c en el kernel de Linux hasta la versión4.10.7 no valida ciertos niveles de datos, lo que permite a usuarios locales provocar una denegación de servicio (colgar sistema) a través de una llamada al archivo ioctl manipulado para un dispositivo /dev/dri/renderD*.

It was discovered that the Linux kernel did not properly initialize a Wake- on-Lan data structure. A local attacker could use this to expose sensitive information. It was discovered that the Linux kernel did not properly restrict access to /proc/iomem. A local attacker could use this to expose sensitive information. It was discovered that a use-after-free vulnerability existed in the performance events and counters subsystem of the Linux kernel for ARM64.
