Xen 'xen_failsafe_callback()' Function Local Denial of Service Vulnerability

Xen is prone to a denial-of-service vulnerability.

Local attackers with access to a guest operating system can exploit this issue to crash the guest operating system, effectively denying service to legitimate users.

Xen 2.6.23 is vulnerable; other versions may also be affected.
