The kvm_arch_vcpu_ioctl_set_sregs function in the KVM in Linux kernel 2.6 before 2.6.30, when running on x86 systems, does not validate the page table root in a KVM_SET_SREGS call, which allows local users to cause a denial of service (crash or hang) via a crafted cr3 value, which triggers a NULL pointer dereference in the gfn_to_rmap function.

Security readout for executives and security teams

CVE-2009-2287 is a Linux KVM host availability flaw. On x86 Linux kernels before 2.6.30, a local user could crash or hang the system by abusing invalid virtual CPU register state. It is mainly relevant to very old KVM virtualization hosts. Exposure is likely limited to legacy x86 systems running KVM on Linux kernels before 2.6.30, or older vendor kernels missing the backported fix. Modern maintained kernels are unlikely to be exposed, but unsupported virtualization hosts should be checked. Treat as a targeted legacy infrastructure risk. It is not a modern internet-facing emergency from the provided evidence, but old KVM hosts can suffer host-level downtime and should be remediated or retired. Mitigation focus: Upgrade affected Linux kernels to a fixed vendor-supported version.; Apply relevant distribution advisories from Ubuntu, Debian, Mandriva, or current vendor guidance.; Restrict local access to KVM device and virtualization management groups..
