CVE-2009-3290

CVE-2009-3290 affects KVM in Linux kernel 2.6.25-rc1 and earlier than 2.6.31 on x86. The kvm_emulate_hypercall implementation fails to restrict MMU hypercalls by CPL, enabling a local guest user to crash the guest kernel and read/write guest memory via unspecified addresses. Root cause: CPL check...
