CVE-2010-2938 – kernel: guest crashes on non-EPT machines may crash the host as well
https://notcve.org/view.php?id=CVE-2010-2938
arch/x86/hvm/vmx/vmcs.c in the virtual-machine control structure (VMCS) implementation in the Linux kernel 2.6.18 on Red Hat Enterprise Linux (RHEL) 5, when an Intel platform without Extended Page Tables (EPT) functionality is used, accesses VMCS fields without verifying hardware support for these fields, which allows local users to cause a denial of service (host OS crash) by requesting a VMCS dump for a fully virtualized Xen guest. El fichero arch/x86/hvm/vmx/vmcs.c en la implementación de la estructura de control de máquina virtual (VMCS) en el kernel de Linux v2.6.18 de Linux en Red Hat Enterprise Linux (RHEL) 5, cuando se usa una plataforma de Intel sin la funcionalidad de Tabla de páginas extendida(EPT), tiene acceso a los campos VMCS sin verificar el soporte de hardware para estos campos, lo que permite a usuarios locales causar una denegación de servicio (caida del sistema operativo) pidiendo un dump de VMCS para un huésped Xen totalmente virtualizado. • http://secunia.com/advisories/46397 http://support.avaya.com/css/P8/documents/100113326 http://www.redhat.com/support/errata/RHSA-2010-0723.html http://www.securityfocus.com/archive/1/520102/100/0/threaded http://www.securityfocus.com/bid/43578 http://www.vmware.com/security/advisories/VMSA-2011-0012.html http://xenbits.xensource.com/xen-unstable.hg?rev/15911 https://bugzilla.redhat.com/show_bug.cgi?id=620490 https://access.redhat.com/security/cve/CVE-2010-2938 • CWE-399: Resource Management Errors •
