    CVE-2012-0218

    Published: 3 Dec 2012Last Modified: 10 Apr 2026

    Summary:

    Details: 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.
