CVE-2009-2287
Linux Kernel 2.6.0-2.6.29 - Denial of Service via KVM_SET_SREGS cr3 Validation Bypass
Title source: llmDescription
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.
