Описание
The KVM subsystem in the Linux kernel before 3.0 does not check whether kernel addresses are specified during allocation of memory slots for use in a guest's physical address space, which allows local users to gain privileges or obtain sensitive information from kernel memory via a crafted application, related to arch/x86/kvm/paging_tmpl.h and virt/kvm/kvm_main.c.
Отчет
This issue does not affect the versions of Linux kernel as shipped with Red Hat Enterprise MRG 2. Future kvm updates for Red Hat Enterprise Linux 5 may address this flaw. This issue was addresses in Red Hat Enterprise Linux 6 via RHSA-2013:0911 (https://rhn.redhat.com/errata/RHSA-2013-0911.html). Please note that unlike Red Hat Enterprise Linux 6, where a local unprivileged user could use this flaw to escalate their privileges on the system, on Red Hat Enterprise Linux 5, Red Hat Enterprise Linux 6.2 EUS, and Red Hat Enterprise Linux 6.3 EUS the impact is limited to potential information leak only.
