In the Linux kernel, the following vulnerability has been resolved:
drm/vmwgfx: use check_add_overflow for shader size+offset bound
vmw_shader_define() validates the user-supplied shader window against
its backing buffer with
(u64)buffer->tbo.base.size guest_memory_offset and forwarded to host SVGA shader-create
commands.
Use check_add_overflow() to detect the wrap and compare the resulting
endpoint against the buffer size.
