CVE-2013-1943

[John Johansen]

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.

Break-Fix: - fa3d315a4ce2c0891cdde262562e710d95fba19e
Break-Fix: - 9e3bb6b6f6a0c535eb053fbf0005a8e79e053374
