CVE-2013-1442

CVE-2013-1442 affects Xen 4.0–4.3.x on CPUs with AVX or LWP. The issue is that XSAVE/XRSTOR state extension of a saved/restored vCPU may leave residual data in registers after touching other extended registers, enabling a local guest OS to read sensitive information from those registers. The vuln...
