Summary

[none]

Details

The vmwgbsurfacedefineioctl function (accessible via DRMIOCTLVMWGBSURFACECREATE) in drivers/gpu/drm/vmwgfx/vmwgfxsurface.c in the Linux kernel through 4.11.4 defines a backuphandle variable but does not give it an initial value. If one attempts to create a GB surface, with a previously allocated DMA buffer to be used as a backup buffer, the backuphandle variable does not get written to and is then later returned to user space, allowing local users to obtain sensitive information from uninitialized kernel memory via a crafted ioctl call.
