As reported by Maxime at https://bugzilla.kernel.org/show_bug.cgi?id=204175: In vmx/nested.c::get_vmx_mem_address(), when the guest runs in long mode, the base address of the memory operand is computed with a simple: *ret = s.base + off; This is incorrect, the base applies only to FS and GS, not to the others. Because of that, if the guest uses a VMX instruction based on DS and has a DS.base that is non-zero, KVM wrongfully adds the base to the resulting address.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
