CVE-2013-1442

Xen 4.0 through 4.3.x, when using AVX or LWP capable CPUs, does not properly clear previous data from registers when using an XSAVE or XRSTOR to extend the state components of a saved or restored vCPU after touching other restored extended registers, which allows local guest OSes to obtain...

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...

Information leak on AVX and/or LWP capable CPUs

ISSUE DESCRIPTION When a guest increases the set of extended state components for a vCPU saved/ restored via XSAVE/XRSTOR to date this can only be the upper halves of YMM registers, or AMD's LWP state after already having touched other extended registers restored via XRSTOR e.g. floating point or...
