+Subject:    [PATCH] drm/vmwgfx: Check check that number of mip levels is above zero in vmw_surface_define_ioctl()
+Date:       2017-03-24 15:37:10
+
+In vmw_surface_define_ioctl(), a num_sizes parameter is assigned a
+user-controlled value which is not checked for zero. It is used in
+a call to kmalloc() which returns ZERO_SIZE_PTR. Later ZERO_SIZE_PTR
+is dereferenced which leads to a GPF and possibly to a kernel panic.
+Add the check for zero to avoid this.
