CVE-2009-2287

Published: 1 July 2009

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.

From the Ubuntu security team

Matt T. Yourst discovered that KVM did not correctly validate the page table root. A local attacker could exploit this to crash the system, leading to a denial of service.
