    CVE-2013-1442

    Published: 30 Sept 2013Last Modified: 10 Apr 2026

    Summary:

    Details: 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 sensitive information by reading the registers.
