Description
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.
Affected configurations
• linux linux kernel (>= 2.6.0 < 2.6.30)
• canonical ubuntu linux 6.06
• canonical ubuntu linux 8.04
• canonical ubuntu linux 8.10
• canonical ubuntu linux 9.04
• debian debian linux 4.0
