∗∗∗ Xen Security Advisory 289 v2 - Spectre V1 gadgets exploitable with L1TF ∗∗∗
---------------------------------------------
A number of specific exploitable gadgets have been identified. There are no new vulnerabilities. There is only new information about existing vulnerabilities: specifically, confirmation that existing, previously disclosed, vulnerabilities, can be exploited in specific ways.

As discussed in XSA-273, disabling SMT / hyperthreading will avoid the L1TF vulnerability. It will therefore prevent the use of the exploitable code patterns discussed in this advisory.
