SCP7-627 : Security Advisory - linux - CVE-2017-9605

Created: Jun 29, 2017    Updated: Sep 13, 2018
Resolved Date: Apr 11, 2018
Found In Version: 7.0.0.25
Fix Version: 7.0.0.29
Severity: Standard
Applicable for: Wind River Linux 7
Component/s: Kernel

Description

The vmw_gb_surface_define_ioctl function (accessible via DRM_IOCTL_VMW_GB_SURFACE_CREATE) in drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux kernel through 4.11.4 defines a backup_handle 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 backup_handle 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.
