CVE-2012-0218
Xen 3.4, 4.0, and 4.1 - Denial of Service via Exception Injection Flag Mismanagement
Title source: llmDescription
Xen 3.4, 4.0, and 4.1, when the guest OS has not registered a handler for a syscall or sysenter instruction, does not properly clear a flag for exception injection when injecting a General Protection Fault, which allows local PV guest OS users to cause a denial of service (guest crash) by later triggering an exception that would normally be handled within Xen.
