CVE-2017-7261 (opens in a new tab)How to fix?
Upgrade Oracle:7 kernel-uek-devel to version 0:3.8.13-118.45.1.el7uek or higher.
This issue was patched in ELSA-2020-5671.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-uek-devel package and not the kernel-uek-devel package as distributed by Oracle.
See How to fix? for Oracle:7 relevant fixed versions and status.
The vmw_surface_define_ioctl function in drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux kernel through 4.10.5 does not check for a zero value of certain levels data, which allows local users to cause a denial of service (ZERO_SIZE_PTR dereference, and GPF and possibly panic) via a crafted ioctl call for a /dev/dri/renderD* device.
